Detailed answer

When the skin is dehydrated, the scalp may become dry and lack moisture. This can affect the health of the hair follicles, leading to hair thinning. Dehydration can potentially disrupt the balance of natural oils on the scalp, impairing the hair growth cycle. Additionally, inadequate hydration can weaken the hair shaft, making it more prone to breakage and thinning. It is crucial to maintain proper hydration both internally and externally to support healthy skin and hair.
