What should you know about dry brittle low porosity hair?

Low porosity describes a hair surface whose cuticle layers lie relatively tightly together. Water or conditioner may sit on top, take longer to absorb, or leave the hair feeling coated. Dryness can therefore coexist with product buildup. Rough handling, hot tools, bleaching, tight styles and repeated washing can weaken the shaft. This label is a hair-care description, not a diagnosis, and the texture can vary across the scalp and lengths.

Apply a small amount of lightweight conditioner to wet lengths and spread it evenly rather than layering many products. Gentle warmth from a shower can help products distribute, but avoid very hot water and direct high heat. Clarify occasionally if residue is persistent, then return to a simple moisturising routine. Detangle from ends to roots, reduce friction from rough towels, and limit bleaching or repeated straightening. If breakage or thinning continues, discuss the cause before considering Hair Supplement Therapy or any supplement.

Seek a dermatology review for sudden texture change, patchy loss, scalp redness, pain, persistent itching, thick scale, sores or thinning at the roots. A clinician can distinguish shaft damage from a scalp disorder and review medicines or health changes. Get urgent help for facial swelling, breathing trouble or a rapidly spreading painful rash.

Is my concern mainly buildup and shaft damage, or is the scalp involved? Which cleanser and conditioner suit my texture? Could a medicine or health change contribute? Should I avoid particular chemical services while the hair recovers?
