@dr.farzan: Low biotin can lead to dull, dry skin and weak, thinning hair because it disrupts keratin and fatty acid production. Correcting the deficiency helps restore smoother skin, stronger nails, and healthier, fuller hair. Hair breakage + dry patchy skin + dry cracked lips can be a sign of low biotin levels!! Biotin: 2,500–5,000 mcg daily (preferably with meals) #lowbiotin #dermatitis #hairbreakage #brittlehair #drylips
