This guide helps you to find out what your hair type is. When you have decided which classifiers are best to describe your hair, you combine all those and get your hair type "code" which will look something like this: 2b C ii/iii. You can use slash and pick two (1a/1b, F/M, ii/iii) if you are not sure.
FIRST CLASSIFIER - Your curliness (or lack thereof)
The straight ones
1a - stick straight
1b - straight but with a slight body wave, just enough to add some volume, doesn't look wavy
1c - straight with body wave and one or two visible S-waves (e.g. nape of neck or temples)
The wavy ones
2a - loose, stretched out S-waves throughout the hair
2b - shorter, more distinct S-waves (similar to waves from braiding damp hair)
2c - distinct S-waves and the odd spiral curl forming here and there
The curly ones
3a - big, loose spiral curls
3b - bouncy ringlets
3c - tight corkscrews
The really curly ones
4a - tightly coiled S-curls
4b - tightly coiled hair bending in sharp angles (Z-pattern)
SECOND CLASSIFIER - What (most of) your individual strands look like
F - Fine
Thin strands that sometimes are almost translucent when held up to the light. Shed strands can be hard to see even against a contrasting background. Similar to hair found on many people of Scandinavian descent. You can also try rolling a strand between your thumb and index finger. Fine hair is difficult to feel or it feels like an ultra-fine strand of silk
M - Medium
Strands are neither fine nor coarse. Similar to hair found on many Caucasians. You can also try rolling a strand between your thumb and index finger. Medium hair feels like a cotton thread. You can feel it, but it isn't stiff or rough. It is neither fine or coarse.
C - Coarse
Thick strands that where shed strands usually are easily identified against most backgrounds. Similar to hair found on many people of Asian or native American descent. You can also try rolling a strand between your thumb and index finger. Coarse hair feels hard and wiry. As you roll it back and forth, you may actually hear it.
THIRD CLASSIFIER - Your overall volume of hair
Put your hair in a ponytail with as much hair as possible in it. Don't bother with the way it looks - the goal is to have most/all of your hair in there. If it means it sits smack dab on top of your head, put it there. Measure the circumference of the ponytail. If you have bangs and/or you can't get all of your hair in there adjust according to how much of your hair you have measured.
i - thin (less than 2 inches/5 centimeters)
ii - normal (between 2-4 inches or 5-10 centimeters)
iii - thick (more than 4 inches/10 centimeters)
TIP: If you are having difficulty determining the thickness of individual hairs, this might help: Take a strand of hair from the back of your head. Roll the strand between your thumb and index finger.
Fine Hair: Your hair is difficult to feel or it feels like an ultra-fine strand of silk.
Coarse Hair: Your hair feels hard and wiry. As you roll it back and forth, you may actually hear it!
Medium Hair: Your hair feels like a cotton thread. You can feel it, but it isn't stiff or rough. It is neither fine or coarse.
ooh this is amazing!
2c C iii

This is pretty great! I never thought I had very thin hair until now.
1c/2a M i
I'm not sure how to distinguish if my hair is 3a or 3b, I think it's probably closer to 3b.
So, 3b M iii
I knew my hair was thick, but even I'm surprised by HOW thick! About 15cm by the way they do it, and that's either without my fringe or without the hair at the back and sides. I can't get it all in.
2a M iii
I'm guessing at the iii as my hair is short right now, but my hairdresser says my hair is some of the thickest he's ever worked with, so I reckon it's pretty thick π
1c F i/ii (I have an undercut so I'm not sure how thick my whole head would be, but not thick :P)
Oh dear, my poor thin hair. How I long for thick luscious curls :'(
Ooh ooh.
1b/c M ii
2b c iii
π
3a C iii π
3a F i
My poor hairs are so thin... π
1b F iii
I always thought my hair was rather thin in volume and fine, but apparently I just about have thick hair and it is fine, not normal; I have fine hair just lots of it!
Boo, fine and thin and pretty straight...1b F i
I guess this is why I lack lustre when long locked :S
1a F iii
My hair is about 11cm of girth with tons of my hair escaping the comb because my hair is medium-short layered, I always thought its thinner but now I wonder what would it be if I was able to gather all of it :O
2c/3a (I have a mixture of waves and loose spirals)/M/ii
Still wish I was a firm 3b D:
I'm a 1b M iii and it reaches my waist π
