Why do people go bald on the top and not on the sides

Why do people go bald on the top and not on the sides

Post  Directo on Sat Mar 03, 2018 7:36 pm

Male pattern thinning occurs when built up DHT binds with receptors in the follicle. This causes the follicle to gradually produce thinner and thinner individual hair stands with each shedding and growing cycle. Eventually the hair is too weak to support the follicle, which then collapses. Once that happens that hair and follicle are gone for good.[...]
We do not have those receptors on the sides. This is also why those rear and side follicles are used for hair transplants. Have you ever seen someone who looks like they had a bad transplant? Those strong rear and side follicles are like tree trunks so they are surgically interspersed among the thinner hair on the crown and vertex. Over time those original hairs disappear completely and leave only the transplant hairs on top, which now look unnatural. Think Cheech Marin from Things Are Tough All Over.
CS, do you agree 100% ?

Eventually the hair is too weak to support the follicle
Isn't the opposite ? The hair does not support the follicle, right ?

The hair bulb supports the hair follicle. The dermal papilla produces the hair follicles.

On the why the back and sides tend to be impervious to balding in classical MPB (Androgenetic Alopecia) is because there are fewer to no receptors in the occipital region and the sides.

No receptors means there is no effect, because there are virtually no nuclear receptors to activate or to be bound by hormones.

I'd second CS. This is the main reason why they don't succumb to miniaturization, and if you pinch the lower back and sides of your scalp you will feel increased layers of fatty tissue beneath the skin. This fatty tissue (and underlying muscles) acts as a cushion, and minimizes compression injury to these cells. The cells of the galea area OTOH have minimal fat layers, thus are more prone to mechanical overload from various factors. IMO pillow compression is a very large factor here.

CS, do these receptors in the follicle have an "official" name ?
Do women have the same receptors (and the same amount) on top of the head ?

Hair loss occurs due to excessive production of DHT, or just due to normal production of DHT ?

Also, the adipose layer in the skin contains stem cells that send molecular signals to the hair follicles. In male pattern baldness, the layer of fat becomes thinner and the absence of stem cells causes the hair follicles to stop regenerating.

The DHT binds to androgen receptors.

there was some study here telling that follicles exert protein that help to generate fat cells .. if this is true then hair follicles will exist before fat tissue .

Men pattern baldness, the top area of the head is temporary section. They not live a long time but it might be live long time through medical treatment, better food and healthy diet, Genetic function.

Badness men and women can get natural hairs through hair transplant surgery.

CS, being bald is having hair which are too small to be seen, or is it literally losing the hair (it's not there anymore) ?
Hair follicles are never dead, right?

And being bald is not "losing hair" but not having properly long enough hair development cycles ? Am I correct ?
Hair are still there but they don't have enough time to grow enough to be visible ?

It can either, because how it's lost depends on the cause. For example alopecia areata (loss of hair) and MPB, miniaturization until the progenitor cells are completely dead (then no hair will be produced).

My bad. I should have been more precise.
I'm not talking about accidents, burning, surgery of the scalp or other MPB. Just in the case of androgenic alopecia with no other health problems.

So what would be your answer then ?
