In my book How Not to Age, I discuss all that drugs, foods, supplements, and surgeries

I can treat age-related hair loss.

But what about non-diatory, non-drug, non-surgical interventions?

Autologous platelet-rich plasma, where concentrated portions

of your own blood, is repeatedly injected into your scalp, appears to have an efficacy

similar to the available drugs, though the available evidence is considered insufficient

to recommend it, and so remains unapproved in the U.S. or Europe

for hair restoration purposes.

Scalp Botox is also not recommended.

The thought was that relaxing scalp muscles might improve blood flow, but when actually

put to the test actually caused hair loss and some pilot studied participants. Then there are lasers.

In the 1960s, a Hungarian physician published the paper

the effect of laser beams on the growth of hair in mice,

detailing a serendipitous discovery that a low-powered ruby laser

increased the hair growth on the shaved backs of mice.

The mechanism appears to be increased blood flow.

The floodgates opened when the FDA cleared the first low-level laser therapy device

for age-related pattern hair loss in 2007.

And now there are clinics advertising lasers for everything from tennis elbow to

scrotal rejuvenation.

There have been at least ten randomized control trials of low-level laser therapy devices

for hair loss, and the efficacy has been found comparable or even superior to the drugs.
