Hair breakage occurs when the hair fiber breaks along the shaft due to weak points in the structure of the hair. Hair strands lose resistance to stretching and get weaker after physical or chemical damage to the hair shaft. Damaged hair has an increased tendency to break because it doesn’t have the flexibility to withstand the stress of everyday wear and tear.
Virgin hair can undergo stretching of up to 30% of its initial length and contract back to the normal length without being damaged. Stretching 30% to 70% of the initial hair length leaves irreversible changes in the hair shaft while stretching to 80% of the original fiber length will cause breakage.
Hair fragility occurs most frequently in individuals with very curly hair who are rarely able to grow their hair long. Their spiral-shaped hair causes increased friction during brushing and styling which can damage the cuticle, increasing the chances of breakage. Straight hair is easier to brush since combing friction is low and there is no risk of severe damage when exposed to mechanical stresses.
What Causes Hair Breakage?
Common hair care habits that impart unwanted damage and trigger hair breakage are excessive shampooing, heat styling, drying hair products, and chemical hair treatments such as a chemical straightening, perms, and permanent hair coloring.
Studies show the number of broken hair fibers increases with chemical treatments. Chemical processing such as straightening, permanent waving, lightening treatments, and coloring can compromise the integrity of the cuticle layer, contributing to frizzing, tangling, and split ends.
Chemical straightening and perming involve changes in disulfide bonds within the hair fibers, leaving the strands with decreased tensile strength and increased brittleness. Permanent hair dyes affect the chemical bonds in the hair cortex and disturb the cuticle layer, leaving the strands weak, inelastic, and vulnerable to breakage.
Hair breakage often occurs when chemical treatments and products are over-used or applied incorrectly. When chemicals are left on longer than the recommended time or are not properly rinsed out hair strands can become excessively dry and fragile.
Blow drying and flat ironing using extremely high temperatures can cause hair to become brittle and weak. The heat sucks moisture from the strands and affects the integrity of the hair fiber, leaving hair dry and vulnerable to breakage.
Pulling hair into a tight bun, ponytail, or braid on a regular basis can create excessive tension and increase the likelihood of breakage. You should also refrain from using uncovered rubber bands and sharp hair accessories that pinch or pull your hair and cause knotting, increasing the risk of breakage.
Improper Brushing and Combing
Excessive combing, as well as brushing hair when wet, can increase friction and cause mechanical damage to the cuticle, leading to weakened hair fibers. Another factor that often contributes to hair breakage is the hair’s tendency to get tangled. Pulling through the tangle creates overstretching and bending that can cause hair fibers to break.
Hair Care Products
The frequent use of poor quality shampoos and styling products that contain alcohol can leave your locks dry and ready to snap. The chemicals from hair care products can build up on the hair over time, making it more susceptible to breakage when brushed.
Nutritional deficiency, aging, hormonal imbalances, and certain medical conditions are often contributors to hair breakage. Environmental factors such as hard water and continual exposure to sunlight can also weaken hair and exacerbate breakage.
How to Stop Hair Breakage?
Hair doesn’t have a self-repairing capability, so broken hair fibers cannot be restored. However, you can prevent hair breakage and split ends by adjusting your hair care routine. Hair breakage can be significantly reduced by restricting the use of chemical and heat styling tools and selecting appropriate hair care products.
Keep your Hair Well Moisturized
Since dry hair breaks easily, it is important to keep your locks well-moisturized. Moisture provides the disulfide bonds in the hair cortex with the flexibility to retract to a normal state after stretching.
Avoid daily shampooing because too frequent washing can remove the protective oil coating from the strands, leaving your hair overly dry and less elastic. Look for a sulfate-free shampoo that will provide gentle cleansing without stripping off all natural oils from your hair and scalp.
Apply a good moisturizing conditioner after shampooing to reduce friction and replenish the lost moisture.
Treat your hair with a deep conditioner once a week to help it stay hydrated and smooth down split ends.
To limit physical stress to the hair, do not brush your hair roughly. Use your fingers and a wide-toothed comb to gently untangle your locks. To minimize the risk of breakage, start from the tips, and then gradually work to the roots.
To avoid overstretching the strands, do not tie your hair very tightly. Choose elastics, headbands, and hair clips made of smooth and hair-friendly materials that will not cause knotting and breakage.
Reduce Heat Styling
Give your hair a break from using heated tools. Air dry your hair if you have time, or use a blow-dryer at a lower setting and with continuous motion. If you can’t move away from hot tools, use heat protection products to minimize the damage from heat.
Have regular trims to get rid of damaged ends and prevent further breakage. If you do not have your hair trimmed for a long time, splits can travel up the hair shaft making the strand weak and ready to snap.
Minimize Use of Chemicals
Avoid overlapping chemical treatments and keep a recommended gap between two chemical processing. Minimize the use of styling products that contain drying alcohols and other harsh chemicals. Switch to organic hair care products to keep your hair in good condition and more resistant to breakage.
Do Hot Oil Treatments
Natural oils like coconut, almond, and extra virgin olive oil are excellent home remedies for hair breakage. Doing a hot oil treatment once a week strengthens the strands from roots to tips and provides your hair with much-needed moisture.
Apply Hair Straightening Masks
Try a homemade hair mask that nourishes and strengthens damaged hair. Apply a mayonnaise or avocado hair mask if you want to revitalize your strands and prevent further damage and breakage.
