As the hair follicles miniaturize, they produce weaker shafts that are susceptible to falling out at the root, or breaking.
The Genetic Aspect of Baldness
It is important to understand that DNA provides instructions for creating protein structures in the body. Those who inherit the genes for pattern baldness (from either the mother or the father) will have DNA codes that synthesize sensitive protein receptors on the hair follicles.
Both men and women have the testosterone hormone in their bodies. When this breaks down, a compound called DHT is produced. When DHT is in contact with the sensitive proteins, this will cause the follicles to miniaturize. They will either produce thinner hairs. Or the hair shafts will fall out altogether.
The Role of UV Rays
While hair loss is mainly dictated by genetics, the extent to which it manifests can be influenced by the environment. Therefore attempts to restore the original quality of hair can involve sun protection.
Many people are unaware of how UV rays can facilitate hair damage and hair loss. This energy can affect both the scalp and the hair shafts themselves.
UV rays can create free radicals from regular oxygen molecules on the skin, causing them to lose electrons and become unstable. They will then target other molecules to acquire electrons and regain stability. This sets off a chain reaction that damages tissue structures beneath the skin. And this can have an adverse effect on hair follicles, causing them to shed hair.
Also UV rays can damage chemical bonds in the cuticle (outer layer) and the cortex (center) of the hair shafts. These structural changes can lead to breakage, dryness and frizziness.
Pigment changes and premature greying can also occur as a result of UV rays.
Hair Sunscreen To Prevent Hair Loss and Damage
Although most people think of sunscreen as something that is used to protect the skin, special formulations are now being developed for the head. This is especially recommended in restoration of the hair in those who are seeing the signs of baldness or thinning.
Since sunscreen is often made as a thick lotion, manufacturers like Redkin are creating sprays that can be applied to the hair and scalp without leaving a greasy appearance. Additionally, there are also conditioners and gels that can be used for protective purposes. The active ingredients of hair sunscreens will either form a protective barrier on the outside of the follicle (e.g. Zinc oxide, titanium dioxide), or they will create chemical reactions within the follicles to protect against UV rays.
Just as there is a concept called sun protection factor (SPF), some products also a new term called hair protection factor (HPF).
Hair restoration efforts can involve sunscreen products. And it is also important maintain a well balanced diet, rich in vitamins, proteins and omega 3 fatty acids. These are all elements that enhance the functioning of your cells and help optimize the body’s ability to synthesize hair.
