Zinc Thymulin

Zinc Thymulin (ZT) is used to regenerate hair lost as a result of androgenic alopecia. Hair loss occurs in a large percentage of the adult human population and increases in prevalence with increasing age. Hair loss may occur in males and in females but is more prevalent in males. In the western population it is estimated that 50% of the male population have noticeable hair loss by 50 years of age. The most common form of hair loss in men is termed androgenetic alopecia (male pattern baldness). Most hair loss involves inactivation of hair follicles, that is, hair follicles cease to grow hair. Literature also suggests that the thinning of the fat scalp layer due to age can contribute to hair loss through inactivation of the stem cells which regulate hair growth. A deficiency of Zinc will also lead to hair loss.

Zinc and thymulin are two natural compounds involved in hair follicle growth and have been studied and found to promote hair growth. Combined into a spray solution, ZT can be applied to the scalp and treat hair loss, bald patches and as well as initiate the angen hair growth phase (the active growth phase of hair follicles during which the root of the hair is dividing rapidly).

Testing has shown to be safe and effective, with proven clinical results published in the peer reviewed medical journal Hair Therapy and Transplantation.  

We know what zinc is, what is thymulin?

Thymulin is a nonapeptide hormone derived from the thymus gland. Early reports of thymus extract stimulating hair growth was discovered in 1986 and 2000. The activity of the hormone is reliant on the mineral Zinc, which is why it is referred to as Zinc Thymulin. ZT also induces differentiation of T-cells.  

Benefits of ZT:
  • Can improve hair growth
  • Can improve quantity of hair
  • Can prevent hair loss
  • Can improve endogenous hair pigmentation
  • A variety of alopecia states can be treated
  • Both women and men can be treated
  • Treatment may be combined with known other hair restoration methods 
Side Effects:

In the study “An Analysis of the Safety and Efficacy of Topical Zinc-Thymulin to treat Androgenetic Alopecia“ Zinc Thymulin demonstrated no adverse systemic effects or local side effects of redness or scalp irritation or deterioration of hair color, quality or quantity. 


Topical applications of ZT demonstrated safety and established efficacy for initiating and maintaining anagen to treat male pattern baldness when applied for 6 months.
