The LOIS Hair System

Sometimes Andre Walker’s number/letter hair typing chart gets a little confusing because it is so subjective as certain hair types can look like all or none of the categories given the state or condition of our hair at the time. However, the LOIS System focuses solely on the shape of our curls as opposed to the size of the curls. Some find this hair typing system to be more generalising but more identifiable.

LOIS describes the bends in the curls or kinks as they will resemble the letters:

LOIS System
L                                               O                                                    I                                                 S


L- If the hair has all sharp bends, right angles and folds with little to no curve then you are daughter L.

O- If the strand is rolled up into the shape of one or several zeros like a spiral, then you are daughter O.

I- If the hair lies mostly flat with no distinctive curve or bend you are daughter I.

S- If the strand looks like a wavy line with hills and valleys then you are daughter S.

Side note: You may have a combination of the L,O,I,S letters. For example, ‘LO’ or ‘IL’ or ‘OS’.  I am a combination of O and S.


 Which category do you fall into?
