Thymuskin: Does the Thymus Gland Even Play a Role in Hair Growth?

I have been using thymuskin a topical shampoo and dropper solution made in Germany by Klett-Loch gmb. The company claims it reduces or inhibits DHT in the scalp, acting as a coating/membrane around the follicules. It is also a synthetic thymus extract/peptide originally from a baby calf, cow but is now synthetic due to cattle health, the German company claims. They say it also acts by boosting the level of thymosin and or boosting the thymus gland which normally shrinks in size. They say it was originally developed for chemotherapy patients that lost their hair after chemo, but soon they say the German doctors who were bald themselves started using the thymus product with success. It is extremely expensive to me @270.00 for a 2 month supply. Does thymosin and or the thymus gland play a role in hair follicule stimulation and or growth? Why did the chemo patients not lose hair when using it while under chemo? I ordered it because I thought with all the products out there, that surely a German company would not lie! It dosen’t suit them based on their history. haha funny. thanks Dr. Rassman

To my knowledge, nothing topical inhibits DHT production on the scalp, though there are some shampoos that claim to reduce scalp DHT. In my humble opinion, it is probably just marketing hype, but if it works as promised, the company can make a fortune selling it at any price worthy of putting in the effort. The Thymuskin North American distributor claims the product was sold for 20 years in Europe, but the amount of years a product is available in the European marketplace really doesn’t have any bearing on its effectiveness. The user reports online vary wildly, and with so many Thymuskin resellers and affiliate links out there looking to cash in, it really makes it hard to distinguish what is a real review and what is a disguised advertisement.

The thymus gland does not play a part in hair growth. There is an association between hair loss and the thymus gland in a special type of inherited disease, but that would not point to the use of any thymus extract in the treatment of the normal genetic hair loss that is common in the general population. I’m not sure what T-cells have to do with hair growth or hair loss, but these cells are in the critical path for autoimmune diseases. Again, in my humble opinion it is just marketing hype, but I will be glad to be proven wrong.
