FAQ

Application, Time & Patience

Is there a rebound effect with the 8T3 Essentials Hair Serum, similar to minoxidil?
None has been observed so far. Individual variation cannot be ruled out entirely, but the general pattern shows steady, continuous growth of newly activated hair.
Is long-term use of the 8T3 Essentials Hair Serum necessary?
The application is structured in two phases: an induction phase at normal dosage, followed by a possible maintenance phase with reduced dosage or frequency. Long-term full treatment is not necessarily permanent.
When can first changes realistically be expected with the 8T3 Essentials Hair Serum?
Some subjects saw first effects after 3 months. The experts recommend at least 6 months of use to ensure results can be reliably assessed.
How does the result typically develop over several months?
First effects become visible after 3 to 4 months and increase noticeably after 6 months. Subjects who used the serum for 1 to 2 years show a steady, continuous increase in hair growth.

Description

Consistent use over time is what allows the 8T3 Essentials Hair Serum to work. The experts recommend at least 6 months. Some subjects saw first results as early as 3 months, but effects become more pronounced and reliable after the 6-month mark. 

The longer the treatment, the clearer the outcome. Subjects who used the serum for 1 to 2 years show a steady, continuous increase in hair growth. Unlike some other products, no rebound effect has been observed so far. Individual variation cannot be completely ruled out, but the general pattern is steady ongoing growth. 

Long-term full treatment is also not necessarily permanent: after the induction phase, a maintenance phase with reduced dosage or frequency appears to be a viable option.
