what is cm2?

[joe32]

what is the numbers used to measure cm2 ..what do good hair transplant doctors offer and what is normal hairs cm2 thanks,,

 

[flimflam]

It's about this:

depending on how close your face is to the screen. obvz.

 

[antonio666]

in hairloss terms it genrelly means how many hairs per cm2

a person who does not have male pattern baldness has on average about 220

 

[joe32]

so whats the best density doctors can do , im sure its important to ask before i get a hair transplant ..

are u saying you can fit 220 follicles in that little box ..lol

 

[antonio666]

Sorry joe32.

i don't mean 220 follicles,i mean 220 hairs

the average person has about 100 follicles per cm2

and there are people who have 220 follicles per cm2,but these people are rare and have very,very dense hair but it is possible

This info should help:

Hair Density, Numbers of Hairs, Rate of growth
The average human scalp measures approximately 120 sq. inches (770 sq.cm).
The hair covering varies numerically according to hair colour and ethnicity.

Caucasian hair type: The figures quoted are based on research published by Drs. Erasmus Wilson, Withof & Stelwagon in the nineteenth century and are therefore in inches.
Blonde 146000 hairs, diameter measuring 1/1500th - 1/500th in.
Black 110000 hairs, diameter measuring 1/400th - 1/250th in.
Brunettes 100000 hairs, diameter infinitely variable
Titian (Red) 86000 hairs, diameter infinitely variable

Afro hair type: Colour is predominately black. Hairshafts are multi helixal with a wool-like character. Healthy individuals possess between 50000-110000 scalp hairs.

Mongolian (Asian) hair type: Possessed by the greatest numbers of people worldwide. Hairshafts are predominately straight. Colour is predominately black. Regional variations exist, but healthy individuals possess an estimated 80000-140000 scalp hairs.

So if I've lost 12,000 hairs out of the 100,000 I was born with with dark brunette hair, I'd need probably 7500 original density hairs added(so hairs from back and sides) to get a thick result. This would give me 62.5 g/cm average over the thinning areas. I'd probably do 70-75 at the hairline and then steadily decrease it to 60 behind it, then 55 in the midscalp.

At 2.4 hairs per graft on average, from what I've heard, I'd need 3125 grafts.

I question the validity of any hair loss reseach that states these figures.

I do not think most people have 100 FU/cm2 all over their heads (non male pattern baldness) only in the donor regions. FU's vary over different regions.

Non male pattern baldness people probably have the same density everywhere. But there are degrees of male pattern baldness. Some guys never recede, but they thin a little on top, so they are not as thick on top. I still think that is a degree of male pattern baldness, though, even if they are counted as average.

Jayman, your numbers sound optimistic. I paid for 4000 follicular units to an area about 100 cm2. Dr Keene said I have 90 hairs, and 60 FU per cm2 in my thick donor region. As I look at my hair now, the recipient area is so thin that I think it is about 1/3 density.

You tell me what numbers you think are wrong. I'm sure some of them are.

Didn't you say earlier though that you believe a lot of your grafts didn't grow? Is it possible that you may have achieved good density with those numbers if all the grafts grew?

 

[CCS]

True. It is hard to say what the precent is, though, or it it is just a few places. It is also important that they go the right direction. All of my recent grafts go in a different direction from the rest of the hairs on my head, making them stand out and give me a messed up look. But half have started going the right direction, and it looks a lot better now.

Yeah, Jayman's numbers could be right. I've looked at a lot of women's roots, and I think about 80-100 FU per cm2 is normal. Maybe 70 on the courser ones.

i do think they are right ccs.

do you agree with the roughly 100,000-110,000 hairs on the head for brunette/black haired caucasians?

how many of those hairs would you estimate are left visible on a completely slick bald on top NW6? I would estimate maybe 20,000 are left on the sides and back. Am I wrong? So if we say 20,000 are left, and the area that is now slick bald used to have 80,000, and the average person can get maybe 6k grafts out total for a total of maybe 13k grafts, how would that not leave a see through donor area?

It's coming up on a yr and the hair still undergoes changes in hair cycle. I'm glad to hear there is some improvement.

what are you saying? all you did was quote me with no response.
