I know it's anecdotal but i will share my experience with it also. I was very reluctant about it like i was with everything that i have found about hairloss treatments, whatever anybody says there is to much controversy and contradictory information about everything related to hairloss and not only but i will stick to the subject. This whole controversy and contradictory information makes it really hard for someone who actually has a brain and uses it to make a valuable and intelligent decision especially when you know that things could go wrong and that your health could get affected, your future, bla bla.
Because of my research i decided to not go on finasteride whatever the costs of hairloss will be, i tried minoxidil and it only made things worse to a point where my hair was effectively destroyed from any aspect, from growth phases to scalp dryness and hair quality, i admit tho that i didn't researched it so well before starting to use it and just trusted a big dermatologist who advised me to use and how to use it, if i knew then what i know now i would have never started it in the first place, but that is another story.
After a lot of research on Keto, i decided to give it a try but not with the cheap usual and common Nizoral with 2% Keto in it and after a lot of searches and documentation i have found Regenepure DR with only 1%, did not buy it from start and kept postponing it until a few months ago when i got it and started using it once a week. My hair quality before using it was really poor, my hair cycles were really fucked up and i really and strongly think that minoxidil did some permanent damage to some of my hair, even if i stopped using it and had almost one year without it and regardless of the fact that others could say that it was just my normal hairloss pattern progression and that these things would have happened anyways even if i would have not used minoxidil in the first place, i call it bullshit and nobody knows exactly what my experience was with it and so on, so i won't get into those kind of discussions.
Now coming back to Keto and Regenepure DR, after a few uses, once a week, i started to feel my hair very different, it felt like it's gaining life again, it started feeling healthy and growing faster, my scalp felt very good and without any sign of seborrheic dermatitis, pimples, oily or whatever, when i touch it and feel it, it reminds me of the days when it was in it's "prime" and healthy as f***, i really did not expected such a positive experience with it. Now i did some things before starting keto also, i stopped washing my hair with any type of shampoo, first i said that i won't wash it with something that has sulfates or parabens in it and after i started washing it daily only with water, after a few months it started to not get oily anymore, it just started to feel better overall and i started dermarolling without anything once a week with an 1.5mm dermaroller and some diet and stress management changes also.
Now i'm not saying or suggesting that it's gonna stop my hairloss or that it's gonna reverse it even if i'm starting to see hairs all over the place but it clearly does something for the health of the scalp and hairs, i am very pleased and upset that i did not started it earlier. Keep in mind that every possible study on hairloss and androgenic alopecia states clearly that the balding scalp has problems with over productive sebum glands, with a lot of types of scalp eczema, Malassezia yeast, dandruff, oily scalp, dryness and so on, there are a lot of factors that are causing them, from genetic and hormonal to immune system problems and much more, it's not just as simple as it sounds, "DHT is killing take finasteride and that's that", if it would have been the case everybody who took or takes it would have had a full head of hair.
