Hair Type 1, 2c, 3c, 4b, 4c

Hair Types 3b, 3c, 4b, 4c

Hair is categorized by hair type, hair texture and shape. What is known in the industry as “Hair Type” 1, 2a, 2b, 2c, 3a, 3b, 3c, 4a, 4b, 4c, should really be called hair shape.


Normal Hair

Normal Hair has balanced sebum; it is not too oily and not too dry. The hair has shine, sheen and vibrancy to it.

Dry Hair

Dry hair lacks sebum. It looks dull, brittle and frizzy. Dry hair has split ends and may have dry flakes.

Oily Hair

Oily hair has excess sebum. It looks weighted down, lacking body and looks dull. Oily hair may also have oily flakes. The imbalance can be from diet, hormones, health issues, medications and product use.


Hair texture is determined by the diameter size of each hair strand.

Fine Hair

Fine textured hair feels soft and is often called “flyaway” hair.

Medium Hair

Medium textured hair feels smooth and soft. It is in between fine and coarse.

Coarse Hair

Coarse textured hair feels rough and thick. It is usually curly or wavy.


Hair shape is decided by the cross-sectional appearance and the diameter size. You can have several shapes of hair.

Curly Hair – Type 3a, 3b, 3c

Curly hair strands are usually dry, brittle, fine and fragile. The cuticle scales do not lay flat and don’t allow moisture to penetrate.

Kinky Hair – Type 4a, 4b, 4c

Kinky hair has lots of twists and bends and is very fragile.

Wavy Hair – Type 2a, 2b, 2c

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.

Straight Hair – Type 1

Straight hair cuticles lay flat; therefore, oils and ingredients can easily attach to the hair and weigh it down.
