is going bald related only to genes? or could it be also related to the chemicals used at hair salons?

It's related mostly to genes. The main determinant of androgenic alopecia(genetic pattern baldness) is a recessive gene on the X chromosome, for guys, inherited only from the mother. This means that while a female needs two of these recessive genes to experience androgenic alopecia, one from the mother and father, a male needs only one. There also must be a sufficient level of DHT(dihydrotestosterone.) Testosterone is converted to DHT by the enzyme 5 alpha reductase, so its level must be sufficient. The best indicators are the hair growth pattern of the father, and the hair growth patterns of the mother's brothers.

For hair loss due to androgenic alopecia(genetic pattern baldness), some have regrowth in the crown area with minoxidil/rogaine and in the crown and frontal area with propecia, but these are better at limiting loss than promoting growth once loss has occurred and propecia has negative side effects. Due to the side effects of propecia, some use the supplement saw palmetto rather than propecia though it works differently. Propecia reduces levels of the enzyme 5 alpha reductase which results in lower levels of DHT. Permixon, the extract of the saw palmetto plant works by limiting DHT uptake at the hair. Even though saw palmetto is available without a prescription, it should only used by teens under a doctor's supervision.

A hair grows for four to seven years to a terminal length, whether cut or not, falls out and is replaced by a fresh hair. Average hair loss and gain is estimated to range from 50-150 hairs per day. The issue is the hairs gained are not noticeable. When hair is thinning due to androgenic alopecia, the terminal lengths become progressively shorter and the hairs become finer until they resemble nearly invisible vellus hairs. The average rate of hair growth is 1/8" per week.

Hopefully, in a few years, research in hair cloning and multiplication will make a full head of hair possible for any guy throughout his life.

Good Luck!

"keratin treatments." Yes.

They also contain FORMALDEHYDE CAUSING CANCER.

Keratin are not approved by the FDA. The FDA does not restrict the use of that chemical in cosmetics.

By contrast, beauty salon owners and stylists generally lack a scientific background and don't have a keen awareness of the danger of working with products that contain formaldehyde, experts say.
