How Does The Sun Damage Hair?
The sun emits ultraviolet light, which is known to damage skin cells, including the cells on the scalp. If the scalp cells are damaged, this can disrupt the healthy structure of the hair, interupting hair growth and contributing to the formation of weak hair that is damaged and prone to breakage. Also, when the hair strands are overexposed to sunlight, it can damage the outer layer of the strand (the cuticle), which can cause the hair to be dry and frizzy, as this damage affects the hairs ability to retain moisture effectively. When the hair is damaged it also becomes more prone to being affected by environmental and styling habits, causing further damage to the hair.
Signs Of Sun-Damaged Hair
Sun-damaged hair often shows a combination of these signs:
Dull or faded colour
Rough, coarse texture
Dry ends prone to breakage
Tangling and frizz
Increased brittleness
Can You Protect Your Hair From The Sun?
Whether you have healthy or damaged hair, you may be wondering whether the sun has potential to cause any damage to your hair and if there are ways that you can protect it from damage helping to keep it as healthy as possible. During the summer, or during times where your hair is exposed to sunlight for prolonged periods of time, there are a few things to consider in order to keep your hair in the best possible condition.
What Are the Ways To Protect Hair from Sun Damage?
Fortunately, if you have been in the sun and think you may have overexposed your hair to sunlight, there are steps you can take to prevent further damage from the sun, as well as ways to repair the damage that may have already been caused. Here are some ways to maintain healthy hair by protecting it from sun damage:
Cover the hair
By physically shielding the hair from the sun, you will be preventing the UV rays from reaching the hair strands and scalp cells, protecting them from damage. If you are exposed to sunlight and your hair is covered from direct sunlight, you will be minimising the extent to which the sun is able to reach the hair and cause any damage.
Use a protective hair sunscreen
You can shield your hair by applying a protective sunscreen that is suitable for both the scalp and hair. A product that protects the hair from UVA and UVB rays will effectively prevent the sun from altering the hair cells on the scalp and damaging them , as well as help the hair strands to be protected from the sun. When in the sun, it is important to use a haircare product that contains UV filters, as when UVB rays reaches the hair it can contribute to the damage of the keratin structure of the hair, weakening the hair, making it dry, brittle, and prone to breakage.
Use a hydrating and nourishing hair oil
Applying a hydrating hair oil to the hair after it has been exposed to UV rays can help to restore moisture loss caused by the suns damage to the cuticle and scalp. The more hydration that is applied after any damage to the hair, the more effectively the cuticles will be able to lie smoothly, retaining more moisture so the hair stays hydrated and is less dry over time. By replenishing the scalp with hydration, it will prevent irritation to the follicles, encouraging healthy hair growth. The general temperature of the sun can also contribute to dehydration of the hair, so a hydrating hair oil will help to replenish the hair after sun exposure.
Avoid adding more heat to the hair
If your hair has recently been exposed to sunlight, it is a good idea to try to avoid using heat on the hair completely, or minimise the use of heat as much as possible. This is because if the hair has been damaged from the UV rays, it is important to not add any further damage to the strands. Following sun exposure to the hair, it is best to incorporate protective haircare methods in order to prevent further hair damage, as well as adding as much hydration and nourishment as possible, to help replenish the hair and make it as healthy as possible again.
