Best Sun Protection for Hair

Human hair is very susceptible to damage when exposed to the sun. If your hair is dry, fine, dyed, or previously damaged by chemical treatments, it is more likely to be damaged by the sun than healthy hair. The damage will be greater if the hair is soaked with salt water and then dried in the sun.

The melanin pigment located in the cortex acts as a natural sunscreen that protects the hair by capturing and neutralizing UV-induced free radicals. However, after long periods of sun exposure, the melanin granules can become bleached and degraded.

How Does the Sun Damage Your Hair?

The main unwanted effects of prolonged sun exposure on your hair include dryness, weakened structure, and color fading.

Dryness: Harmful sun rays destroy the protective coating of natural oils, making the hair look dull, dry, and porous. Sun-induced damage is particularly noticeable on the outermost layers of the hair, called the cuticles, which are receiving the highest level of harmful UV radiation. Damaged cuticles lose their ability to keep moisture inside the hair which results in excessive dryness.

The weakened hair’s protein structure: Lifted cuticles lead to increased porosity, split ends, and brittle strands. A damaged cuticle cannot protect the inner part of the hair shaft from external damage. Sun damage, then, could affect the cortex and weaken protein bonds that are responsible for hair strength and elasticity. The outcome is an increased likelihood of hair breakage.

Color fading: Healthy hair cuticles reflect light and prevent UV rays from penetrating the pigment-containing inner cortex. A damaged cuticle cannot block UV rays from breaking down pigments in the hair cortex. That is how sun rays can cause color fading and give your hair a bleached appearance.

Sun exposure reduces the color vibrancy of dyed hair as well as virgin hair. Gray hair is even more susceptible to damage when exposed to sunlight because it lacks the protective pigment melanin.

How to Avoid Sun Damage to your Hair

1. Avoid exposing your hair to intense UV light. The sunlight is the strongest between 11 AM and 3 PM. When you’re going to spend the day outside, shield your hair and scalp from the sun by wearing a sun hat or a scarf. A quality sun hat creates shade to provide UV protection, but it still allows the hair and scalp pores to breathe.

2. When you spend a lot of time in the sun, wear protective styles such as braids to reduce the exposure of your hair to UV rays.

3. After each swim, use fresh water to remove the salt or chlorine from your hair.

4. Use sulfate-free color-safe shampoo and conditioner.

5. Use the lowest heat settings when styling your locks to avoid further damage.

6. Apply a deep-conditioning treatment at least once a week to restore the moisture levels and keep your hair more resilient to damage and breakage.

7. Use natural oils such as coconut, castor, or olive oil to provide gentle protection to your locks during periods in the sun. You can also purchase sun protection spray for hair made from UV protective oils such as AVEDA Sun Care Protective Hair Veil.

8. Avoid coloring your hair just before going on a summer holiday because this will make your hair more susceptible to sun damage and will shorten the time between color appointments.

Sunscreens for Hair

UV-absorbing filters or sunscreens are included in hair care products to neutralize the harmful effects of the sun’s rays on hair structure and to protect color pigments from fading.

To shield hair from sun damage, many companies offer complete product lines with sunscreens in their formulation. Their shampoos, rinse-off conditioners, masks, leave-in conditioners, and hairsprays contain UVA/UVB filters to provide a high level of sun protection.

To get full protection, use a wide-toothed comb to distribute the product evenly throughout your hair. You also need to re-apply the sunscreen to your hair regularly throughout the day.

Leave-in conditioning products with UV filters give your hair good sun protection and help it retain moisture.

Paul Mitchell Color Protect Locking Spray is advertised to protect your locks from damage and prevent color fading when you are out in the sun.

Scalp Sunscreens

How to Refresh the Color after Summer Holidays?

To refresh your hair color after the summer holidays, apply a hair gloss/glaze treatment. This treatment will impart shine and restore the tone of your original color until the next regular coloring service.

If you have blonde or gray hair, use a nourishing purple toning mask to get rid of brassy tones and keep your color bright.
