Quick Tip: Hair Typing (L.O.I.S. Hair Typing System)

There are multiple hair typing systems, but I prefer * the L.O.I.S. Hair Typing System (developed by the people of as it is the most descriptive and encompassing.  I believe that defining the hair on your head is a step closer to understanding what you're working with.

*I relate hair typing to horoscopes: cool to know, but I'm skeptical about the overall impact.

L.O.I.S System: 

You will need: A freshly washed and dried hair strand that is representative of the most common type of hair on your head. This strand needs to be a healthy, undamaged, virgin hair strand (one that is not processed, relaxed or colored).

Find Your Pattern:

L - If the hair has all 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.

You may have a combination of the LOIS letters, possibly with one dominant. If you cannot see one letter over the others, then combine the letters. Example: LO or IL or OS..

Find Your Strand size:
A strand of frayed thread is about the thickness of a medium sized strand of human hair. If your strand is larger than this, then your hair is thick. If your strand is smaller than this, hair is thin, or fine..

Find Your Texture:
Shine is a sharp reflection of light while Sheen is a dull reflection of light.

Thready - Hair as a low sheen, with high shine if the hair is held taut (as in a braid), with low frizz. Wets easily but water dries out quickly.

Wiry - Hair has a sparkly sheen, with low shine and low frizz. Water beads up or bounces off the hair strands. Hair never seems to get fully wet.

Cottony - Hair has a low sheen, a high shine if the hair is held taunt and has high frizz. Absorbs water quickly but does not get thoroughly wet very fast.

Spongy - Hair has a high sheen with low shine with a compacted looking frizz. Absorbs water before it gets thoroughly wet.

Silky - Hair has low sheen, a very high shine, with a lot or low frizz. Easily wets in water."

My Hair Type:  

For reference, I have an SO combination, medium to fine strands, high density, and cottony hair texture. What is your hair type?


  1. O, fine strand, low density, spongy.

  2. SO, spongy, fine strands
