Clinical and practical context for 1B Hair

1B Hair describes observable fiber curvature and packing on intact, minimally manipulated strands. It is a cosmetic classification, not a medical diagnosis. Research papers more commonly reference measurable traits— diameter, ellipticity, lipid content, and damage to the cuticle—than consumer letter codes, but the codes remain useful because they align with how products are marketed and how stylists communicate with clients.

If you notice abrupt texture change together with scalp pain, circular bald patches, or shedding that clogs your drain, prioritize evaluation by a board-certified dermatologist or qualified trichology clinic before adjusting your routine based on typing alone.
