As we age, Hyaluronic Acid levels in our body decreases. Such an assumption can be hold true even for the dermal cells around our hair follicles and it can be among the reasons why, as we get older, our hair become dryer and brittler.
The marvellous hydrophilic properties of Hyaluronic Acid is able to deliver onto our skin are well known in the Health & Wellness community, but less scientific evidence is available regarding its effects on the hair. Still, according to many trichologists’ opinion, it looks like HA’s humectant properties may perform similarly onto both cuticle and hair fibers. Absorbing moisture from the atmosphere and holding on to it, Hyaluronans make hair more hydrated and elastic, thus healthier.
This process works especially well on extremely dry and damage hair fibers, which, for being more porous, find it harder to naturally retain moisture. In filling these holes and covering the hair, water-bound Hyaluronic Acid makes the fibers healthier and more resilient to everyday stress factors, such as the mechanical action of combing, heat styling and brushing or the damage of environmental agents like smog.
Furthermore, natural HA such as SinoHyal has the ability to stimulate neovascularization, encouraging the creation of new blood vessels on the scalp, a natural mechanism that helps oxygen to reach hair follicles and contrasts damages brought by genetic, dietary, stress or chemicals factors.
Hence, including Hyaluronic Acid in formulation for hair fibres and cuticle helps us to protect against natural brittleness caused by everyday life or natural aging processes, donating smoothness, volume and brightness to our hair.
