Hello guys, I've seen people experience hair loss on this forum for a while now and decided to help with knowledge I've gained from university and from the experience of losing hair my self.

Hair loss will be dependent on a few factors:
1. How many androgens are in your system.
2. Androgen receptor sensitivity and how prone you are to follicular miniaturization from endogenous or exogenous androgens
3. The types of androgens in your system (DHT from your natural Testosterone’s conversion, as well as the androgenic activity of Testosterone itself)

Now, as a male, you will have significant more levels of testosterone then a girl, so any women reading this shouldn’t worry. Unless they’re using drugs that increase testosterone and or DHT derivatives. The tradeoff of being a male, is you have a lot of DHT circulating inside your system. Now what is DHT? Dihydrotestosterone (DHT), or 5α-dihydrotestosterone (5α-DHT), is an endogenous androgen sex steroid and hormone that is a by-product of one’s own Testosterone levels.
Testosterone is the primary sex hormone in men, that gives men the male characteristics such as, deeper voice, beard, and body hair. While it’s good for the wife, it’s not entirely good for your hair. Testosterone its self isn’t what you should be worried about, but DHT. The reason being DHT is more androgenic, but also because it has a much higher affinity to bind and miniaturize hair follicles than Testosterone does.

This hormone binds to receptors in the hair follicle. Over time, this causes the hair to shrink. Eventually, it becomes so small that it stops producing hair.

Let’s look at an example, DHT derived drugs are often the strongest in terms of size and strength gain. Trenbolone (DHT) will pack size on you that Testosterone (DHT by-product) its self can’t do in the same amount of time frame granting ALL variables are CONTROLLED. DHT steroids in general are more powerful.

According to American Hair loss Association, “Androgenetic alopecia or common male pattern baldness (MPB) accounts for more than 95% of hair loss in men.” Hair loss is closely related to DHT and most people will experience it, “By the age of thirty-five two-thirds of American men will experience some degree of appreciable hair loss, and by the age of fifty approximately 85% of men have significantly thinning hair”.

Way’s to prevent it going from light to aggressive.

1. Nizoral shampoo. I know, shampoo? But the main ingredient, Ketoconazole can actually combat DHT directly. It is just a normal anti-dandruff shampoo; however, it contains Ketoconazole, which is a powerful antifungal that removes the buildup of DHT in the hair follicles.

2-3. Finasteride or Dutasteride. Both of these drugs reduce 5-alpha reductase and thus DHT levels. The % depends on the drug and the amount you’re taking. Finasteride is the most common FDA approved drug for hair loss. When taking this drug, make sure not to take Deca-durabolin otherwise it will make hair loss worse.

1 mg of Finasteride reduces DHT levels by 70% (https://www.ncbi.nlm.nih.gov/pubmed/8077349)
1 mg of Dutasteride reduces DHT levels by 90%

4. Another way to prevent it is RU58841, unlike Finasteride and Dutasteride, it is applied topically, reducing the effects of DHT locally, rather than systemically. There is strong clinical evidence that ru 58841 drastically reduces the effects of DHT directly to where it’s applied(head). However, it’s not clinically approved for any medical use. However, it’s a research chemical and can be used for experiments and research purposes.
