I’ve had dandruff and an itchy spot on my head. It really doesn’t respond to any shampoo and I know it’s part of a bigger thing because when it gets worse a few other areas around my body get really dry and start to itch. Wtf.

I leave the floor coated in hair wherever I go but I have a super thick coat of hair, even with shoulder length, it takes a ton for it to dry
It's been months like this and no notorious change, but as the video says, probably has to do with Ballet hahah

My mom has alopecia, and she has no hair at all.
I was wondering, is it genetic?

"menopause can affect someone's..." you can tell "menopause can affect a woman's..." is being avoided, because men can undergo menopause now.

One time I suddenly developed alopecia barbae which caused a small, circular bald spot in my beard (which was still visible even after shaving because it was completely hairless) and it was caused by stress and went away after a while.

Why are men and women storing fat differently. What´s the advantage of storing it mostly in the belly, rather than spread over a wider area? Since, we´re already on topic: why do many Afro-american women have butts that seem to defy gravity (not sagging, less bouncing and no moon-surface)?

My hair started falling out in 2017. It happened because I was very ill and on a lot of medications. I got better, came off the meds and it started to grow back thicker. Now I have a tonne of baby hairs that aren’t yet long enough to tie up but are long enough to get in my eyes...

I actually have alopecia areata I always thought it was stress related. My dads a barber and in barber college he learned about hair disease and the way hair grows and he told me what it was and that it’s mostly stress related and it’ll grow back so I never really looked in to it I mean it’s probably only happened like 4 or 5 times in 3 years.

I have dandruff. It started around 12 years of age. I've tried all kinds of dandruff shampoos none work. I have to only shampoo my hair once a week sometimes twice. I use shampoos for Africans because they're not as drying on my scalp. I also have to oil my hair once a week to two weeks. My son whose reaching 12 years old just developed dandruff too. I think its a hormonal thing rather than a fungus thing as you mentioned. Why would it only start around the time hormones change in a person's body? I'm so tired of dealing with dandruff.

John Smith They are using very precise language to describe exactly what they are referring to in each case they refer to sex, gender, or biology. When they say all genders they are including humans who are intersex, because the thing they are referring to is equally applicable in everyone’s case. Science is well aware there are more than 2 biological realities.

Lucky Like one hair, on your head? Sounds kinda neat to me, but if you dislike it just pull it out. It may grow back sooner or later, and for some reason white hairs can seem to grow way quicker than any other hair, but you can just pull it out again. No big deal.

Thanks SciShow for talking about alopecia areata. I have alopecia universalis which is a form of AA with total hair loss over the entire body. AA is one of the least understood and under-researched autoimmune disorders out there since there is no physical pain/restrictions. However, the negative psychological and societal effects can lead many of us to develop mental illnesses among other side effects. Any coverage on our disorder is appreciated as we collectively are trying to create awareness to fast-track research and clinical trials. Woohoo!

Am sorry but u really need to add other medical conditions and to go to ur dr for more deep eval.. Like a lot of dandruff for a person that never had it might be HIV sorry meant to say medical emergency symptoms.. or stop using others ppl brushes.. Ringworms causes bald patch on head.. ur body has a self warning signal to u to say hey go to the dr or something is wrong here do something before us to late. Just a little more in depth would b nice alway end with see a professional.. like excessive hiccups 4 days might also b a signal for the autoimmune disease hiv saying hey have this check out by a dr.. someone with halitosis should not blow food for a baby.. or kiss u u will get that bacteria .. meds can also do damage to the human system

I had adult cradle cap!!! It was so weird. I think it could've been partially because I'm a model, and people are always putting weird products in my hair that I have no control over. I also traveled a lot and lots of different phs in the water etc, i suppose could contribute to the microbiome. I also just think it's important to scrub your scalp a bit with your nails, I read somewhere that this causes irritation so I stopped scrubbing my scalp with my nails, just my fingertips, and the buildup became more severe. Sometimes you gotta just dig in there!! Hah.

When I was in my teens I had a brief interesting period where two or three small patches of hair on my body just lost all pigmentation; My doctor couldn't work out why but put it down to some sort of stress reaction 🤷🏻‍♀️
(The pigmentation never return to those patches either)

I learned a crapton about telogen effluvium after I started losing clumps of hair a few weeks after recovering from dengue fever. I know it's just hair and that it grows back, but suddenly losing that much hair so quickly is really distressing. It's been two years since the rapid hairloss stopped, but I feel like my hair has not gone back to how thick it was before TE.

How to get a thick healthy hair:
- Eat healthy (for a light blood);
- Hidratare enough (2 litres of water per day);
- Don't stress or get upset (because the stress hormones attack the hair follicles);
- Go outside and get some vitamin D (but don't stay to much in the sun), or take vitamin D medicals if you are a vampire;
- Wash it 1-2 times a week, especially if work in dusty places (no more often);
- Don't excess with the comb or with special sprays/gels (try to let the hair free, natural, to breathe);
- Be happy and laugh often.

victorpapaavp When my grandpa grew a beard, it had a reddish tinge to it. I suspect it’s something to do with carrying the allele, but not expressing it. Maybe beard hair is influenced by both alleles? Idk but it’s definitely, like, a thing that happens (facial hair being a different color to scalp hair)
Rachel Losacco

In high school I got mono and was bed ridden for 3 weeks. About a month later, I was pulling my hair out by the handfuls (though I didn't look bald, thankfully). I think it might have been telogen effluvium -- over the next few months the missing hair was growing back and I had an awkward "halo" of new hair on top of my regular long hair. But is it common that it should kick in so much later after my illness?
