Caring for Your Hair after Brazilian Keratin Treatment

Once you’ve had a Brazilian Keratin treatment done, you need to take special care of your hair to make sure that the treatment will last as long as possible. Keratin treatments wash away gradually over time, but with proper care, the results of your keratin treatment will last about 12 weeks.

Brazilian Keratin Treatment and Hair Coloring

If you color your hair, you can do so immediately before a Brazilian Keratin Treatment without damaging your hair or reducing the efficiency of your color or straightening treatment. However, you should wait at least three weeks after the treatment before coloring hair again.

Post Treatment Period

Avoid getting your hair wet for three days after the treatment has been applied. This means no washing, swimming, or sweating—and stay out of the rain. Make sure to give your hair time to blend with the keratin.

Leave your hair down and unstyled for the first few days after a Brazilian keratin treatment. The keratin is still malleable, so if you put your hair in a tail or use a hair clip, it can leave dents in your hair. If you want to tie your hair up, wait until the keratin has been in the hair for at least three days, and then use a soft hair tie for short intervals of time.
You are not supposed to use any hair products during 3-day waiting period, and if your hair does become twisted you need to use a flat iron to smooth it out.

Styling after the Treatment

Blow-dry your hair after washing, but avoid using hair products after the first shampoo. You don’t need root lifting sprays, mousse, hairspray or gels to style your hair after a Brazilian Keratin Treatment. Keratin will keep your hair in the right style without the need for styling products. Chemical-free products can be used, but an overuse of styling products could make your hair look dull and dirty. Instead, blow dry and run a flat iron over the hair to manage your strands into the right style to extend the length of your Brazilian keratin treatment.

After Treatment Precautions

It is also a good idea to wash hair less often to maintain the look longer, because the results wash out gradually. Be wary of exposing your hair to high levels of chlorine or salt water, and always cover your hair during intervals of high UV levels, as these factors will reduce the life span of the treatment.

Wear a cap when swimming. The salt from the ocean and chlorine from swimming pools can wash out your Brazilian keratin treatment. If you won’t wear a cap, take a shower before you go swimming, soak your hair, and comb in conditioner. The water will help fill your porous strands to avoid chemical absorption, while the conditioner will add a level of protection.

Keratin Aftercare Shampoos

In the months following the treatment, select a shampoo and conditioning set that is free of sodium and sulfates. For maximum longevity, purchase a shampoo that is specially developed for keratin aftercare. The shampoo will complement the keratin straightening treatment and the results will last longer.

Top Five Shampoo Brands for Keratin Treated Hair

Deep Conditioning

Use a sulfate free deep conditioning masque at least once a month. Deep conditioning works to nurture hair and helps extend the duration of keratin treatments. Once the treatment began wearing off a deep conditioning mask helps prevent the effects of humidity, keeping the hair less frizzy, smoother, and easier to style.

Nighttime Care

Sleep on a silk pillowcase at night. Traditional cotton pillowcases can create friction and disrupt hair follicles as we move, making your hair frizzy and the treatment short-lived. By sleeping on a silky pad, you’ll avoid roughing the hair strands when you toss and turn at night. Silk creates very little irritation, which means a longer-lasting keratin straightening treatment.

Brazilian Keratin Treatment Reapplication

On average, a Brazilian keratin treatment should last about three months. After that, your hair will return to its normal state, but it should be healthier and softer because of the conditioning impact of the keratin. Once the effects of the Brazilian keratin treatment have worn off, then you are free to have the treatment applied all over again. The repetition of the process on your hair tends to enhance the quality every time you get it done. The procedure will be done in the same way as it was previously.

  1. For best results it is recommend to color before getting a keratin treatment. The procedure will seal down the color, so it lasts longer and looks more natural.
    Wait at least 2-3 weeks after keratin treatment before getting your hair dyed. To avoid ruining your keratin treatment use ammonia-free dyes.

  2. I work out three to four times a week and do sweat A LOT on my head – will this ruin the Brazilian ?

  3. Avoid any activities that can get your hair wet for the first four days after the treatment. Once your treatment has set, sweating won’t ruin it, but washing your hair too often will reduce the life span of your keratin treatment. Just let your hair air dry after workouts. If necessary use organic dry shampoo between hair washes.

  4. It depends on the choice of formula. A truly formaldehyde-free BKT can be done as often as every month. It’s advisable that you find a hair care professional who is skilled in hair straightening and will help you make the best choice for your hair.

  5. Hi..What kind of serum or cream that will help me to make the hair look shiny n not dry after keratin treatment?

  6. Keep in mind not to overdo with styling products. Your hair can get oily faster and may need more frequent washing. Once the Keratin treatment wears off, look for chemicals-free and silicone-free styling products that will add shine and protect your hair from the effects of humidity.

  7. You may need some blow drying it if you like your hair to be perfectly straight but blow drying will require less time than prior the treatment.
    Try to let your hair to air-dry after washing. Your may find that your hair still looks great.

  8. I just had this done and my hair feels smooth with the exception of a portion on the back/middle. Looks fry 🙁 Is this normal? Straight but looks a little unhealthy

  9. I had a brazilian blowout a week ago. Yes, I have no more frizz due to the humidity in Texas but my hair is so flat. I’ve tried mousse, root lift, drying with a round brush and velcro rollers. Nada. Is there a way to hurry up and get this out of my hair? I hate it. Thanks for responding!!!

  10. The treatment will gradually wash out of your hair. To speed up the fading process wash your hair using shampoos with sodium and sulfates.

  11. Hi..i had my brazilian last week sept 20…can i use other keratin product for the maintenance of my brazilian treatment. Can i use it weekly?

  12. Yes, you can. Make sure that a product you are going to use is free of sulfates and sodium chloride. Keep in mind that overusing styling products can increase the need for hair washing. Frequent hair washing will decrease the longevity of your treatment.

  13. Can I use John Frieda Frizz ease serum on my hair that has had a keratin straightening 2 weeks ago
    Or Dove Pure Care Dry Oil ( I have these products at home)

  14. These products are not naturally based but none of them will do any harm to your treatment. Use styling products in moderation to avoid frequent washing.

  15. Can i use leave in conditioner and heat protection cream before blowdrying my hair from the second wash, if yes which products are goood??

  16. Rene Furterer Lissea Leave-In Smoothing Fluid smoothens hair and protect it from heat when you blow dry. It also helps reduce frizz once your keratin treatment wears off. Joico K-Pak Leave-In Protectant and Burgati Keratin and Argan Oil Professional Series Leave-in Conditioner are also excellent leave in products for chemically treated hair.

  17. Use hair oils in moderation to avoid the greasy look and reduce hair washing frequency. Apply the oil only to your ends.

  18. Don’t rush to get another chemical treatment, please. Be gentle to your hair. Use a mild moisturizing shampoo and don’t use hot water when rinsing your shampoo or conditioner. Minimize heat styling and use a heat protectant when flat iron your hair. Shine and Smooth by Enjoy offers heat protection, provides smoothing effect and enhances shine. Briogeo Rosarco Blow Dry Perfection and Heat Protectant Crème also might be a good choice. Add a few drops of Jojoba oil to your shampoo and conditioner. Do google research for a lightweight hair oil.
    Ask your stylist about Hair Botox or Cellophane hair treatment, or whatever he/she suggests, but nothing with harsh chemicals, please.

  19. I don’t know about your hair type, product you have used or how the treatment was performed. There are many possible reasons that the results are not as desired. Did you follow the instructions? Did you clarify before the treatment? You might have used too much product. Hair sometimes can look flat immediately after the treatment, but this will not last. Using keratin enriched hair care products like shampoo, conditioner, mask and leave in conditioner can help retain natural moisture and make hair softer and more manageable. These products also keep hair stronger and more resistant to humidity. If you want to straighten your hair, make sure to consult professional before the next chemical service.

  20. Thanks for sharing the information, I was looking for broken hair care tips, and I think this website gives good information. Nice website 🙂

  21. Wash your hair as normally, but not too frequently. Make sure to use gentle shampoos without salt and sulfates. When your treatment start to wear of, use keratin enriched shampoos and conditioners and keratin infused hair masks to keep your hair strong, smooth and frizz free and to prolong the time between straightening services.

  22. You can use any quality flat iron to fix small bents during the first 72 hours after the treatment.
    After the treatment is set, it would be best to limit your use of hot tools. When your treatment starts to wear off, ceramic plates with added tourmaline would be the best choice to get smooth, shiny and frizz-free results with minimal damage to your hair.

  23. I had a keratin treatment in November and my hair is falling from the root. Can I use Schwarzkopf Gliss Hair Repair Ultimate Repair Shampoo or will this make the shedding worse. Will my hair grow back? please help me

  24. Hair loss after keratin treatment is one of the common undesired side effects of keratin treatments. The hair loss is not permanent, but it is hard to predict when the traumatized roots of your hair will recover.
    There is no a miracle solution for this problem. Just make sure to be gentle with your hair and avoid harsh chemicals in hair care products.
    Schwarzkopf Gliss Hair Repair Ultimate Repair Shampoo is designed to replenish natural keratin loss and moisture and reduce breakage of severely damaged hair.
    However, this shampoo contains Sodium Laureth Sulfate, which can be harsh on your hair and scalp. Another unwanted ingredient is Sodium Chloride, which can dissolve keratin coating.
    Use a mild, sulfate and salt-free shampoo. If the problem continues, consult your dermatologist.

  25. Dry scalp had a brazilian blowout on December 15,2017. Love it problem with really bad dry scalp what can I uas that won’t damage my brazilian blowout.

  26. Use a hypoallergenic shampoo that is free of sulfates and sodium chloride. Organics Hair Care Shampoo, Fragrance-Free by Desert Essence is worth trying. Always follow with a moisturizing conditioner.

  27. You can use natural hair oils with no added chemicals. Argan oil works well for chemically treated hair. When your treatment starts to wear off, consider a hair oil infused with keratin (such as L’ANZA Keratin Healing Oil Hair Treatment) to tame frizz and smooth your ends.

  28. The suggested shampoo/conditioners are so expensive.. what do you think of the new L’Oréal PureSleek one? Also… when I washed my hair the first time I applied the L’Oréal shampoo twice to get a good cleanse. Is it bad to apply the shampoo twice?

  29. can I use lavender oil on keratin treated hair? because I lost a lot of hair and I know that lavender stops the hair loss… if not what other type of oil I can use to prevent the hair loss

  30. Moisturizing Shampoo for Dry & Damaged Hair with Lavender & Jojoba by Maple Holistics is free of salt and sulfates and therefore safe for keratin treated hair. You might want to see a dermatologist to find the solution regarding your hair loss problem.

  31. Hello,
    I use ACM novophane anti hair loss lotion which contains:
    Ingredients :
    Aqua (Water), Alcohol Denat., Helianthus Annuus (Sunflower) Seed Oil, Pentylene Glycol, Panthenol, Niacinamide, Sodium Ascorbyl Phosphate, Pyridoxine HCL, Tocopheryl Acetate, Biotin, Myrocarpus Fastigiatus Oil, Citrus Paradisi (Grapefruit) Peel Oil, Citrus Aurantium Dulcis (Orange) Fruit Extract, Juniperus Oxycedrus Wood Oil, Mentha Piperita (Peppermint) Oil, Pogostemon Cablin Oil, Hibiscus Abelmoschus Seed Oil, Limonene, Farnesol, Geraniol, Linalool.
    Can I keep using it after keratin treatment?

  32. I cannot see why not. Just make sure to use the product sparingly to eliminate the need for frequent hair washing. As you probably know, the keratin treatment washes out gradually with shampooing.

  35. Using sulfate-based shampoo just once will not ruin your treatment. Make sure to include a sulfate/salt-free shampoo in your hair care routine.

  41. i had my 3rd keratin treatment yesterday and within just a few hours, my hair began to frizz. i do live in a very hot humid climate and was possibly sweating, however this has not happened before. after waking this am, i had waves on the back of my head i haven’t dealt with before either. my question is: can i run a flat iron through my hair to help retain the chemical? i will wait as long a possible for the first wash of course with my kerastase if you believe that’s a good choice. thanks so much!

  42. Hi I have had Brazilian for the last few years and love it as before I had relaxer and would never go back
    I usually have foil highlights done in salon but as the grey I am seeing now is more noticeable in the re growth (darker brown) I would like to DIY the highlights myself. Is there any colour dye I should avoid?
    Thanks

  43. If your hair gets wet in the 24 to 72-hour period following your keratin straightening treatment, blow dry the wetted part of your hair until it is completely dry, then use the flat iron to make it straight.
    Make sure to use salt and sulfate-free shampoo, like Kerastase Discipline Bain Fluidealiste Sulfate Free Shampoo.

  44. Make sure to wait at least two weeks after keratin treatment to do any other chemical treatment on your hair. You can add highlights before the treatment. Consider using a toner to achieve the desired shade, as toners are gentler to your hair than permanent dyes.

  45. Hi, my hair was very dry and brittle. I had the bkt for the first time about 10 days ago. I love the look and feel, except that my hair has begun to break excessively. Please advise The product used is 100% natural. A well known brand

Discuss available option with your stylist.
