I've seen more than a few people concerned with hair loss and thought I might share what I've learned in my years of research. I started noticeably losing hair when I was 16, and I've managed to keep it under control even with the use of AAS through a lot of research and choosing the right compounds. I've even managed to grow some back using other products which will be discussed at the end.
If you aren't prone don't worry you will not lose hair on anything! Look at Boston Loyd and Jay Cutler for example. They run grams of gear and have full heads of hair.

So here's a list of steroids and their ability to cause hair loss in those prone to MPB in MOST cases. Keep in mind dosage and duration of use also matter but this is a rough list:

Almost never causes hair loss:
Turinabol
Anavar (if real)
Deca/NPP (without finasteride!)

Only occasionally causes hair loss:
Primo (if real)
Equipoise
Superdrol
Low dose test (under 500mg a week w/ finasteride or under 300mg w/o)

Will most likely cause hair loss:
Higher dosed test
Trenbolone (if kept to 25mg a day it COULD be ok)
Dianabol

Will almost definitely shed hair if you are prone:
Proviron
Winstrol
Masteron
Anadrol
Halotestin
Cheque drops
M1T
Mtren

What else can you do to stop hair loss besides limiting AAS choices?

Finasteride: This is FDA approved to treat hair loss and works by blocking the DHT conversion of testosterone at the 5-alpha reductase enzyme which is what binds to hair follicles in the scalp and starves them of the nutrients they need. Do NOT use with nandrolone as nandrolone converts to dihydronandrolone (a weaker androgen) in the scalp which is what makes it relatively safe. I personally didn't like using this as it made me feel awful and destroyed my wood. A lot of users report good results however.

Ketoconazole shampoo: ketoconazole is actually an antifungal medication that blocks DHT from binding at the scalp and in turn saves your hair. I've noticed excellent results from this and my preferred shampoo is Regenepure DR. It comes with several other ingredients that have also been proven to help with hair loss. However you can get a generic cheaper shampoo with just the ketoconazole if you prefer.

Minoxidil/azelaic acid: Minoxidil is FDA approved to treat hair loss and although the mechanism is not fully understood, the current theory is that it reopens follicles that DHT has starved of nutrients and allows them to grow again. It is also one of the only things that has been proven to regrow hair! This held true in myself as my hairline is less receded and hair is thicker than when I was a teenager. Azelaic acid essentially works in the same manner as ketoconazole and blocks DHT from binding to the follicle. I get these in a combined form in a product called lipogaine.

There you have it. I hope that helped some people out and don't take "just shave it bro" as an answer.
