Did you know that...
Hygral fatigue can damage the hair due to swelling and contraction of the hair during the uptake and loss of water. As a result, this process can eventually weaken the hair by causing damage to the hair cuticle and cortex.
Swelling and de-swelling of hair is one of the causes of hair damage. If the cuticle is constantly under stress, it will expose the cortex thus causing porosity issues and breakage.
The swelling of the hair shaft is limited by the presence of oil. Coconut oil can be used as a pre-wash treatment (great for preventing protein loss) to prevent the hair shaft from swelling. This may help the cuticle from being raised and exposing the cortex.
Remember that the swelling of the hair shaft can damage the hair cuticle and cortex which can eventually weaken hair.
