You should start using Thymuskin as early as possible, as soon as the first signs of hair loss appear. The sooner the hair follicles are supported, the better the chances of success. In the early stages, improvements can often be observed within about 3–6 months. If hair loss has been ongoing for a longer period or significant thinning is already visible, longer and consistent use is necessary to stabilize and improve the condition of the hair, as the hair follicles are often compromised and the further course of the condition depends on this.
