I would say with that short of a time length, you're endogenous testosterone probably didn't stop producing - at least not completely. You could come off without PCT with probably no problem, but I would get a blood test in 6 weeks to make sure.
Btw, if you're concerned about Hair Loss, I recommend checking out
https://www.hairlosstalk.com/
They have lots of good articles, a forum, feedback from member son various methods of what hair loss treatments work and what don't.
My hairline is starting to recede and I've been using a product called
PURA D’OR Anti-Hair Thinning Shampoo. It has lots of great ingredients that inhibit DHT production at the scalp, including saw palmetto, Pygem, Nettle extract, and they also include
Nizoral (Ketoconazole) which has been shown to block DHT at the receptor site in the scalp. There is also biotin in it of course, which is another supplement you should be taking for hair loss (although the studies are scant).
They also make a very good conditioner called
PURA D'OR Hair Thinning Therapy Conditioner. It has an ingredient in it called
Copper Tripeptide-1 which has been shown to reduce hair loss and possibility even regrow it. Some people use it on their own, and some people combine it with minoxidil.
I use both the shampoo and conditioner daily. I combine the shampoo with another shampoo called
Everclean. It has some
Salicylic acid in it. This helps force the old skin to peel off and regenerate new skin, helping the follicles stay clean and free of debris. Dr. Lee who used to run minoxidil.com (before they f#$king FDA shut him down) sold a formula very similar to this. It was Nizoral and Salicyclic acid as a shampoo.
You can also look into applying
azelaic acid nightly before bed. I see Amazon has a few products with azelaic acid in them, but they're a bit pricey, and I think hairlosstalk sells some cheaper. Here's one I found called
NutraViv Hair Growth Serum. It contains: Purified water, alcohol, glycerin, azelaic acid, black cohosh, pantothenic acid, Japanese green tea extract, aloe, licorice extract, seabuckthorn berry and seed oil, grapefruit seed extract, and niacin.
You can also buy some topical spironolactone from Hairlosstalk. It's a greasy formula and it stinks, so I really don't like using it. Good ole Dr. Lee used to make it into a liquid that was much more easy to apply.
Finally, I take
NOW Supplements, Prostate Health, Clinical Strength. It has tons of ingredients to help with hair loss including saw palmetto, beta sitosterol, Stinging Nettle (Urtica dioica), Pumpkin Seed Oil and lots of other good stuff which will work internally to help slow hair loss.
Btw, if you want to check out Dr. Lee's old page, it's still the wayback machine and has some very good articles.
