People need to read the botox studies again and stop saying that androgenetic alopecia has nothing to do with scalp oxygen levels.

TLDR:
Low-oxygen environment = more testosterone gets converted to DHT
High-oxygen environment = more testosterone gets converted to estradiol
Regarding garlic, I tried garlic+onion+ginger juice for some months awhile ago and it definitely worked to regrow hair, but the sulfur smell was unbearable and I quit. It stays with you for days. If I did it again I would probably mix it with peppermint to neutralize the smell.
Olive oil on the scalp is a very bad idea. I did that mistake. Not only fungi - that cause inflammation and dandruff - feed on oils, they clog your skin pores and trap DHT. DHT is present in sebaceous glands and in sebum itself.
I'm now using the mainstream approach of topical finasteride + minoxidil, microneedling, ketoconazole and tretinoin. Only maintaining, but at least my scalp doesn't stink.
Mechanistically, the scalp behaves like a drum skin with tensioning muscles around the periphery. These muscle groups — the frontalis, occipitalis, and periauricular muscles and to a minor degree the temporalis — can create a “tight” scalp when chronically active. Because the blood supply to the scalp enters through the periphery, a reduction in blood flow would be most apparent at the distal ends of the vessels, specifically, the vertex and frontal peaks. Areas of the scalp with sparse hair growth have been shown to be relatively hypoxic, have slow capillary refill, and to have high levels of dihydrotestosterone.
Conceptually, Botox “loosens” the scalp, reducing pressure on the perforating vasculature, thereby increasing blood flow and oxygen concentration. The enzymatic conversion of testosterone to dihydrotestosterone is oxygen dependent. In low-oxygen environments, the conversion of testosterone to dihydrotestosterone is favored; whereas in high-oxygen environments, more testosterone is converted to estradiol. Blood flow may therefore be a primary determinant in follicular health. Strategically placed Botox injections appear able to indirectly modify this variable, resulting in reduced hair loss and new hair growth in some men with androgenetic alopecia.
