Hair shape is decided by the cross-sectional appearance and the diameter size. Natural hair is predetermined.
Straight hair cuticles lay flat; therefore, oils and ingredients can easily attach to the hair and weigh it down.
Kinky hair has lots of twists and bends and is very fragile.
Curly hair strands are usually dry, brittle, fine and fragile. The cuticle scales do not lay flat and don’t allow moisture to penetrate.
Wavy hair can appear straight, yet with a little humidity, it can become frizzy and curly. The cuticle stands out, therefore sebum (natural oil) does not make it to the ends and this causes dry ends.
