The Hair Shaft

The Three Layers

The cuticle

The Cortex

The medulla

S.Pocklington

The cuticle

• The cuticle is the outer layer of the shaft.

• This is the first layer to show any type of damage

• The closed cuticle feels smooth

S.Pocklington

The cuticle

• The cuticle is slightly raised in this picture

• If you were to run your finger down this shaft you would feel the damage

S.Pocklington

The cuticle

• The damage to this shaft is caused by the hair being over processed when perming.

S.Pocklington

The cortex

• The extend of the damaged cuticle in this picture exposes the cortex.

• This could have been caused by the over possessing of colour treatments.

S.Pocklington

The cortex

• The whole shaft has shattered in this picture.

• This could have been caused by incorrect choice of perm lotion.

S.Pocklington

The cortex

• When you tug wet hair to comb through you stretch the hair shaft, if you tug too hard you will cause this type of damage.

S.Pocklington

The cortex

• Detangling hair from root to point will cause split ends

S.Pocklington

The cortex

• Knotting hair will cause pressure on the cuticle and cortex, leading the hair to break.

S.Pocklington

Healthy looking hair

• Think every time you handle hair you need to be careful not to damage the cuticle.

• When the cuticle is smooth it reflects the light and gives a shiny appearance.
