Honestly Its hard to say how much anything does as because of my heath, ive gone through times of extreme shedding etc... Hell if anything ive been shedding recently...so just my health hurts me body wise, it also hurts my hair... I try to keep it simple but if you are interested in anything I take heres a link to some.. affiliate link but doesnt cost you to click...
https://amzn.to/3gD0kDs Tricomin, best shampoo to get if you are a person who leans towards needing a copper shampoo instead of a zinc person. Not the norm. But there are studies that this kinda person exists and I am one of them. Also not as good as old formula and more expensive but it is what it is.
https://amzn.to/3iTRMtf Revita... another shampoo I liked till they put ketoconzaole back in.. normally though this is probably good for most people as the majority of the population probably could benefit from it, but again just my luck im one of the people that is pretty sensitive to it and have had even outright really bad reactions before.
https://amzn.to/3wINn0w Biotin.. I normally just take a couple.. some people go crazy and take like 5,000+ but i normally just keep it to a 1000 or 2 since i already try to eat healthy in the first place obviously so...
https://amzn.to/2SEOnnKhttps://amzn.to/3iQGNks viviscal.. theres a dude and a girl version.. I actually take the girl version since im prone to becoming anemic from chronic disease anyway plus its generally cheaper to get anyway...
