It is not known to be toxic in any way, and has been shown to have beneficial effects when combined with stem-cell therapy.
The study Thymulin, a zinc-dependent hormone, states at the end of its abstract that “It is not toxic and one may foresee its clinical use as one of the major immunoregulatory agents in the near future.”
A study in 2017 entitled Hair Therapy and Transplantation claimed that participants:
showed a significant increase in the number of newly observed intermediate hairs in previous “absent hair” regions (P<0.0001) with an average increase of vellus type (32%) and intermediate type (23%) hairs at 6 months. Melanogenesis was observed in several subjects
There are a couple of reasons why this can work. One is that it supplements people who may be deficient in Zinc. Zinc Deficiency has been known to cause a number of health issues, one of which being hair loss. However, the more popular idea is due to the fact that Zinc helps in the production of testosterone, which, some believe can help with hair growth. However, other evidence suggests that increased testosterone can cause hair loss.
One study showed that “Zinc supplementation of marginally zinc-deficient normal elderly men for six months resulted in an increase in serum testosterone from 8.3 ± 6.3 to 16.0 ± 4.4 nmol/p (p = 0.02). We conclude that zinc may play an important role in modulating serum testosterone levels in normal men.”
Pretty much no study has been done in regards to zinc supplementation when it comes to hair loss. One case study showed that a patient who had hair loss not due to deficiency benefited from Zinc supplementation, but more research needs to be done.
The evidence for topical Zinc Thymulin is weak at best and non-existent at worst. The only study in existence is done by the same company that provides the treatment options, which can be thousands of dollars for a yearly supply. Based on the lack of evidence for this, I cannot make a conclusion that this product is effective when it comes to preventing hair loss, or encouraging hair regrowth.
How to use Zinc Thymulin for hair loss and where to find it
The only known way to use this treatment is to apply a mixture of the solution directly to the scalp. This is claimed to help boost hair growth. However, not only is it expensive, but it is difficult to find. The only place I can find that offers it as a service is Olympus Stem Cells. Again, it might not be worth it without further evidence substantiating their claims. However, that is up to you.
There’s very little evidence to show Zinc Thymosin can promote hair growth. If you’ve seen a study that I haven’t mentioned that looks promising, please paste a link in the comments section.
Would I try it? Not at the moment. If I see more promising research results I might reconsider.
