    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

    Hmm, didn't hear it mentioned that a persons' thyroid may be out of balance, or there's a nutritional/vitamin deficiency .

    "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.

    Nicely explained, but what causes premature greying of hair, can that be treated? I have seen even the 5 years old kids start to have grey hair.. is it all diet dependent?

  31. Nishant Sengar

    @gingergamergirl98 I thinks it's more to do with your diet, especially if it lacks vitamin b6, b12 and D..

    Too many comments way funnier than me :) Thank you Sci, this happens to the best of us and shouldn't be feared. I had a severe health thing, three months later my hair fell out, three months after I am back to normal. Well, normalish :) Talk to your doc, and we dont judge.

    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 had a telogenic event and it was scary! Happened after I had a thyroidectomy. Lost most of my hair. Thankfully once my thyroid meds were adjusted my hair grew back.

    Well many people look up things on the internet first because at least in America so many people can't afford health insurance also people want to be educated about what's going on with their bodies

    Please make a video about why your turn down the music volume when backing into a parking lot ( and what science is behind it). Yeah for sure it´s because of focus, but why does everyone do it? Maybe there is more to it. Much love, thx for your show!

    If you ever cut it off, consider donating it. Pay it forward in thanks for whatever it gave you. Personally i'm a fan of a good head of hair as long as it is clean.

    Dandruff is caused by fungus. In special shampoos there are ingredients which kill those microorganisms. You are missleading people...

    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.

    Sometimes I get extremely stiff, translucent hairs on my arms (only ever noticed it on my arms) that are very easy to pull out and sometimes there’s are multiple coming from the same follicle. Does anyone know what this is or what causes it?

    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.
