Malnutrition whether due to a deficiency of protein or other nutrients or secondary to a debilitating condition may lead to a dull, brittle and thin haircoat and to dry, scaly skin. This in part reflects the high requirement for dietary amino acids to supply requisite building blocks for epidermal turnover and hair growth. Sulfur-containing amino acids are common in the skin and therefore sulfur supplementation is popular for dealing with skin conditions. | Malnutrition whether due to a deficiency of protein or other nutrients or secondary to a debilitating condition may lead to a dull, brittle and thin haircoat and to dry, scaly skin.
