Hygral Fatigue - Can Water Damage your Hair?

Many of us deep condition our hair.Β It can seem like the longer you leave the conditioner in, the better. What if we told you that this isΒ damaging your hair?Β 

Leaving hairΒ wet for too long can weakenΒ it through a process known asΒ hygral fatigue.

What is hygral fatigue?

What is hygral fatigue?

When hair is wet, the hair shaft expands as it fills with water and it contracts as it dries.Β Each time hair is washed, cracks onΒ the hairΒ structure can occur.Β Hygral fatigue is a weakening of the hair caused by this repeated expansion and contraction of hair each time it is washed. Hair isΒ weakenedΒ by hygral fatigue over timeΒ asΒ damage accumulates inΒ the cortex bundles ofΒ protein that makes up the hair.

Hygral fatigue also causes the protectiveΒ cuticle layers to chip away as the hair swells and contracts.Β 

The result of hygral fatigue is breakage, limp weak hair and split ends.

How can I avoid hygral fatigue?

There are two main ways to avoid hygral fatigue. The first is before washing. The second is when drying.

Before washing, applying a polarΒ oilΒ can reduce the chance of hygral fatigue. Polar oils are able to bind to proteins inΒ the hair shaft meaning that fewer water molecules can bind to the hair and so less swelling occurs. Coconut oil has been proven to protect againstΒ hygral fatigue by preventing swelling.

Drying hair quickly also helps. When hair is wet, time is of the essence. The faster hair is dried, the less opportunity there is for damage to the hair structure. Heat damages hair so we recommend using a special hair drying microfibre towel turban for optimum results.

Try coating hair in coconut oil and covering with a shower cap for a few hours before you wash it. Let us know if it makes a difference!
