Sun is no doubt the best source of Vitamin D that nourishes your skin and hair. But if your hair remains exposed to the sun for a long time, it will also destroy it. Yes, it’s true. On summer days when you go outside for a long time, you always put sunscreen on your skin to protect it from any type of sunburn and damage.

But did you ever apply any hair serum/product to shield your hair and scalp from harmful elements? Your answer would be No, and that is the main cause of hair damage that we never understand. 

The sun contains UVA and UVB rays that are harmful to hair, skin, and scalp; if you are being exposed to the sun for a long time without covering yourself. Whether we are going to the beach for a sun bath or visiting any place where your hair and skin are exposed to the sun; you should apply something to protect them from breakage and dryness. Most of the hair issues start growing when you reveal them in sun for a prolonged time.  

Does sun damage hair? 

Some people do not believe that the sun can ever destroy the health of your hair and scalp, but unfortunately, it does. A certain amount of sun rays are good for your physical and mental health but you know the phrase very well that excess of everything is bad. Yes, the sun can damage your hair; not only the external layer but internally too. 

The large amount of UVA and UVB are not only harmful to hair texture, but they can also destroy color tone and cause dryness and frizziness in hair. We will discuss some of the types of damage, the sun can do to your hair and scalp. 

Colour damage 

The natural color of your hair can also be affected by sun rays. If your hair is exposed to the sun most of the time, the original color of hair will get faint and your hair will turn into some golden tone. Because the UV rays will bleach down the original color of your hair.  

If you have dyed your hair, then you should protect it from an extra amount of sun rays because dyed hair is already fragile. If you excessively expose them to the sun then the color will wash out and make the hair look dry.  

External damage  

The outer layer of the hair i.e. cuticle provides moisture to the hair and protects the shine and smoothness. But prolonged exposer to the sun will damage it. And it will not able to protect the hair completely, resulting in dryness or frizzy texture of hair.  

Internal damage  

As UVA and UVB rays damage the outer layer of hair and you can lose the shine and silky texture of hair. So if you continue to reveal the hair to the sun, it will come up with great hair damage or baldness. Your hair may internally get weak and split ends will start growing. Hair may become easily breakable and you will lose all your shiny beautiful hair because of negligence. 

Continued contact with the sun will damage the protein of the hair. Protein deficiency will create dullness and hair loss issues. So when you are going outside in an open environment, apply something to prevent any hair damage.  

What are the signs of sunburnt hair? 

Different types and textures of hair can face different hair issues from sunburnt. Sun damage is dependent on the build of your hair. Mostly straight and colored hair is prone to sunburnt because they are sensitive and have less level of resistance than dark and curly hair. 

Dark-colored hair tends to tolerate the sun rays without being damaged but light-colored hair is very fragile to bear any UV rays. Similarly, thick hair is stronger and less likely to get any harm from the sun. But if you note any change in color, texture, or dandruff in hair, do contact a dermatologist or perform home remedies to control it.  

These sun damage signs may include; discoloration of your natural hair, silky-shinny hair turned into rough and dry strands.  Lots of split ends start to occur and hair becomes brittle and easily breakable. The fine texture will convert into cracks and frizz will appear that make you very uncomfortable. If you find these signs in your hair then it’s time to apply DIY or consult your doctor.
