Daily hair loss normal at 100 hairs/day

A local doctor told me that it’s normal to shed 80-100 hair a day, but hairloss starts to occur when these shed hair are not replaced., Is this right?

We all shed about 100 hairs per day and replace that same number. IF you calculate that we have approximately 100,000 hairs on the head (typical Caucasian) and with a 3 year hair cycle between anagen and telogen, the growth cycle in a typical male is about 3- 3 1/2 years.

Daily hair loss in shower and elsewhere

I’ve heard it’s normal to lose over 100 hairs throughout the day, but every time I wash my hair and towel dry it’s seems I’m losing a ton of hair. I’ll shampoo and each time I run my hands through my soapy hair and look at them there’ll be close to or over 10 hairs and appears like it adds up to almost 100. No matter how many times I run my hands through my hair I’ll see a bunch of hairs. Then, if I towel dry with a white towel I’ll see even more hairs. Is it normal to lose this much hair just in the shower? I shower every day but wash my hair every two to three days.

The average hair loss per day for an average Caucasian male is 100,000 hairs, but I doubt that you would lose them all in the shower unless you are losing more than 100 hairs per day which would occur in a hair loss situation. When you rub hair that is miniaturizing, these hair easily come out with your fingers, your towel and almost anything you do to rough up your hair.

Dad Lost Hair in His Late 30s, I’m Losing Mine at 20

Hi Doc. Really nice blog! Been so helpful!

Just want to know. Is it normal to see hairloss several years before your dad did? I’m balding in the age of 20. My dad began losing hair in his late thirties.

All the best!

It seem you are an early bloomer. Hair loss can start as early as teenage years and doesn’t necessarily follow the exact timeframe as other family members. I suspect what you are going through is normal… for you. You need a good diagnosis with a doctor who will map out your hair for miniaturization to help make the diagnosis. Drugs like Propecia can slow or stop the balding process and change the course of hair loss over time.

My Dad Has Hypothyroidism and Developed Hair Loss as I Am Now Doing.

I am taking good care of myself with a 1000 calorie diet and daily exercise, but I am losing hair anyways. Can I have a thyroid problem?

Both hypo and hyperthyroidism can cause hair loss and precipitate genetic balding if you have the genes for balding. You need to see a doctor and get your thyroid checked out. Also, your extreme diet can cause balding to appear especially if you have the genes for balding.

Dad bald, 3 brothers bald 1 brother not bald, what are my chances?

Dad is bald at 68 but I he had most of his hair at 30 I think

Eldest brother at 31 is balding at the back but barely any hair loss, don’t think his temples are bad but would never notice

Next brother at 28 shaved his head

Next one at 25 shaved his head

Next one at 22 has significant hair loss noticeable when he puts his hair up

What are my chances? It is supposed to be a 50/50 on the mom’s chromosomes yeah?

Please god help me as this is ruining me

If you are 16, you won’t know yet. As you get closer to 21, you might see some balding changes. By the time you are 26, you will know. If you want to know in advance of what you see, connect with a doctor who has a HARICHECK instrument (https://baldingblog.com/haircheck-test-how-it-is-done-video/) and have your hair measured yearly which will pick up early balding before you can see it.

Cytostatic Agent on the Face and Eyebrow Hair Loss?

Hello doctor,

can a cytostatic agent applied to the face in order to relieve effects of seborrheic dermatitis cause damage to eyebrow hairs? As far as I know, it slows down cell multiplication rate of the skin so I am wondering if it affects eyebrows and how?

Thank you

I think this question is better asked to a dermatologist. I have no experience with cytostatic agents as they are used for the treatment of seborrheic dermatitis.

Cyproterone Acetate and DHT

Dr. Rassman,

I know this may sound like an odd question, but, would an antiandrogen such as Cyproterone Acetate reduce the levels of DHT in the male body? Would it preserve hair in a person with very little balding. I realize there are major side effects with this drug, but am still curious.

Thanks, and keep up the wonderful work, your blog is quite informative!

Anti-androgens in men can cause a chemical castration, so yes, I would say that the side effects are major. A castrated male has no sex drive and may lose facial and body hair. Cyproterone is not something I’d suggest fooling around with.

The direct answer to your question comes from Wikipedia: “Some in vitro studies have suggested that cyproterone or cyproterone acetate may have a slight inhibitory effect on 5-alpha-reductase, however no significant reduction in DHT production has been observed in vivo.

Cyberhair — Synthetic Hair Fibers

I went to this place to try cyberhair. They tied three artificial hairs to one of my own hairs and did this for a total of 100 hairs. After the procedure, there was pain in the area that they worked. A few hairs came out from the procedure. Is this legitimate?

Cyberhair was developed by Aderans, a large maker of wigs and owner of hair transplant chains Bosley and Medical Hair Restoration (which has recently merged under the Bosley name). It’s just a type of synthetic hair fiber that is braided to your existing hair, a technique that has been around for many years.

The biggest problem in having artificial hair braided to your own is that in many cases it causes traction alopecia. This results in progressive hair loss from the constant tugging on the original existing hair.

Cutting Proscar?

When you cut a proscar pill into 4 pieces does it lose it’s effectiveness ? Where do you store the 3 other pieces ? I heard that oxygene lower the potency of the drug

NO, but you should only cut one pill at a time and use it within the week, keeping it dry in a pill bottle because you don’t want it to take up water from the air around the pill.

Cutting One Follicle to Make Two

When a hair is extracted with FUE, why doesn’t it grow back? I mean, couldn’t you just extract the greater part of the follicle, and leave a small portion still in the dermis, and it could generate two hair, like follicular multiplication?

When performing the FUE procedure, you may potentially transect the follicle, thereby damaging it and causing the hair to not grow. The other possibility is that if the follicle is left behind without damage, then it might regrow. What you are postulating has been a study that was done by many people and published in medical journals (an interesting article that addresses this is: “Cloned” Hairlines: The Use of Bisected Hair Follicles to Create Finer Hairlines).

Basically, one hair will not make more than one hair. When a hair is cut in two, one part dies and the other part may grow, but if it does it is often thinner than it was before the damage was done.
