Use the shampoo and serum regularly for best results, preferably in conjunction with each other.

Safety Warning Consult a doctor before use, especially if you suffer from a disease, are pregnant or breastfeeding. See more Review: Fantastic - I started with the Med serum first as my hair fall was quite significant. I used 2 x bottles of Med serum before I moved on to the classic. My hair has never been this healthy. Highly recommend for anyone battling with hair fall and thinning. Just be patient and diligent with your usage. Review: Very expensive and very disappointing - I have given this product a low rating, I have used it intensively for 5 months at a considerable cost to no effects and I am very disappointed, after researching it I had high hopes. I can only conclude it works on some people and not on others. I would not recommend this product at all, I am still using the shampoo as it gets my hairs clean and is gentle on the scalp. I have tried to give direct feedback on the Thymuskin web site but strangely I can't get the " contact us" to work! This is the second time I have written a negative review for this product and I will be disappointed if it's not shown. ## Features - Against hair loss and to activate new hair growth - Stimulates the growth of hair cells.

My son has male pattern baldness on both sides of the family, and he wanted to try this product when he was around 19. Since it’s a little pricey I bought it every year for his birthday until he was old enough to afford it himself. He may still be using it, at age almost 43. He’s not a chrome dome and he has some hair on the top with the hairline somewhat receded. We have no way of knowing if he has more hair than if he had never used it, but I’m sure he’s glad he was better safe than sorry, All in all, no harm done. **Q: is the sls good in this shampoo i thought it was bad to use** A: What is sls? **Q: Does this contain parabens?** A: I am not sure. I was please with the results I achieved from the product. **Q: Is this the gel?** A: This is Thymuskin Serum. It is Step 2 of the Two Step System (A shampoo and A Serum). THYMUSKIN® Serum is applied directly onto your scalp allowing the active ingredients to reach the root of the hair follicles which helps with the activation and stimulation process. There is also a Styling Gel that Thymuskin makes. However, this is a completely separate product and should not be confused with the Serum. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fantastic *by B***N on 8 June 2025* I started with the Med serum first as my hair fall was quite significant.
