Uncle didn't have any tips for a receding hairline by any chance?

Transplant hair from nose to head, perhaps?

I don't want _that much_ hair, jeez :-)

Hit the gym? Lol.

To increase testosterone and speed up the onset of baldness?

I don't think working out increases testosterone

> I don't think working out increases testosterone

You think wrongly, they're definitely linked:

"Exercise: Resistance training increases testosterone levels acutely, however, in older men, that increase can be avoided by protein ingestion. Endurance training in men may lead to lower testosterone levels." [0]

>however, in older men, that increase can be avoided by protein ingestion.

Why on earth would you want to avoid it? That's like saying weight loss could be avoided by eating lots of cake.

It's an interesting question, I'm not sure. This is mentioned under the Health Risks section though:

"In people who have undergone testosterone deprivation therapy, testosterone increases beyond the castrate level have been shown to increase the rate of spread of an existing prostate cancer."

So there's probably myriad scenarios where one needs to balance testosterone levels with maintaining physical activity/strength training.

if we included testosterone supplements I think we'll find a correlation

Taking testosterone increases testosterone? You must be joking

the correlation is with the gym

Correlating gym-going with testosterone supplementation?

One rabbit hole to go into for this topic is Diindoylymethane a.k.a. DIM which is a Indole-3-carbinol but there are caveats that vary by person, dietary intake, environmental intakes, genetics, etc... It affects how much testosterone and estrogen are converted into their less potent forms but it's tricky because it would have to be measured in the blood serum first to avoid taking too much, otherwise the conversion inverts and/or other weird things start to happen.

Finasteride.

In extreme corner cases estrogen seems to keep it from happening.

It works even better if you rub your belly at the same time. Not a lot of people have that kind of coordination tho.

Doesn't help hair.

Wow! Thank you

The What I've Learned YouTube channel recently did a video on this! https://youtu.be/Yehk_h_Uj6k

Hard to refute -- I use a pretty vigorous spin-brush-dryer on my hair every day for ~5 minutes, which only does the top and front. I just noticed recently that the sides have grown out beyond a few mm, and they are much grayer than the top.

Doesn’t everyone grey on the sides first?

maybe microvascular stimulation helps hair follicles lifecycle

There is a subreddit dedicated to hair loss and techniques. I think one of the highly rated posts discusses use of weekly dermarolling, massaging the scalp, in combination with the regular things like finasteride, minoxidil, and ketoconazole shampoo. Anyways, this isn't exactly science. I think one mode of action to explore is increased blood flow helping with hair growth.

We know massaging an area increases blood flow to that area, in turn promoting better cellular metabolic processes. Dermarolling seems to do this through inflicted trauma/irritation to said area. I know one of the actions of minoxidil is a vasodilator.

Checks out. Worst case you just have really clean hair and developed a new daily mindfulness technique.

Oh wow. My father went bald. As a teenager i didnt want that to happen so to my stupid teenage mind it made sense to vigorously massage my head when I washed my hair. It is still lush at 54.

Pretty sure it was just genetics, but i still do the same thing 40 years later and now I am afraid to stop.
