It takes time to regrow hair. Some men will start to see visible results after 2 months, whereas other men may need to wait up to 4 months before they see visible results. At first, you can expect to see small, thin hairs appearing, similar to baby hairs. These hairs should get thicker and darker over time and become similar to your other hairs. The full results of the treatment can be expected after 9-12 months.
It’s important to point out that if you don’t see significant results within the expected time frame, you shouldn’t start using a higher-than-recommended dosage. This will not increase the speed at which you start seeing results, and may increase the risk of developing side effects.
