Type 1A
Pin-straight, fine, and glossy.
Type 1A hair is poker-straight from root to tip with a fine, silky texture. It reflects light beautifully but can fall flat and look oily fast because natural sebum slides easily down the smooth strand.
Quick answer
Type 1A is straight hair: pin-straight, fine, and glossy. It pairs best with low and medium porosity. Use ingredients like Hydrolyzed silk, Panthenol, Light argan oil, and avoid Shea butter and Heavy mineral oil. The top product pick is Briogeo Scalp Revival Shampoo (shampoo).
