Over-hydrating hair is a thing - yes, you can give your hair too much hydration which results in hair fatigue! Over hydrating can lead to the hair shaft swelling and contracting excessively, weakening the hair structure over time. Signs to look out for include limp, overly stretchy and easily breakable hair.
To avoid over-hydration, balance moisture with protein treatments, as protein strengthens the hair shaft. Additionally, avoid excessive use of water-based products and deep conditioning treatments - balance out the use of these products as much as possible. Maintaining this balance ensures your hair remains healthy, resilient, and less prone to damage.
