A bad time for hair is at night when the grey cells of the sweat glands release perspiration, which is highly charged with toxins and lactic acid.
People under stress of emotional problems wake up in the morning with lifeless, limp hair that looks slightly greasy near the roots. This is an indication of the presence of lactic acid. A typical aspect of hair suffering from the scalp hyperhydrosis is that it becomes fine, limp, lifeless, discoloured and dry on the ends.
The hair keratin gradually becomes porous due to the loss of ceramides, which bind the cuticle together, including essential elements, minerals and moisture.
Not only does hyperhydrosis affect the hair structure, it can also threaten the life of the hair itself. Lactic acid not only attacks the cuticle but also the protective epithelial sheath, which locks the bulbs inside the scalp.
