It is true that caffeine does penetrate the skin easily ( 5). Furthermore, when applied topically, it is primarily absorbed through the hair follicles. This makes it very suitable as a topical treatment for hair growth. These claims from the makers of Plantur 39 are straightforward and accurately reflect the science. Is Plantur 39 Okay for Younger Women? However having used this for 6 months, I can't see any benefit gained from this, if anything, I may have lost more hair (not due to plantur 39 but just not helping enough perhaps). Anyway, again, journey continued to searching for what works. I came across another similar hair product, in a soap form (Called Taoist Soap) designed for the scalp and use for hair. I'm not related for that company, but i must say, only in the second month, I can already see my hair falling rate is decreased, I almost have no hair falling in the shower or bed anymore. Only thing I changed was using this soap 2-3 times a week, and then use normal fragrance free shampoo on other days. I am a male and over 40.

Dr. Wolff, the maker of Plantur 39, also has another popular shampoo line for men, Alpecin. However, the active ingredients in both lines of shampoo are almost identical. Most of the Plantur products contain synthetic caffeine, and they are all targeted at women over 40. Why? Below is a summary of the main positive and negative points that users of Plantur 39 have highlighted online. The GoodPlantur 39 recommends that you use their shampoo and conditioner often. In addition, they also recommend using the Plantur 39 tonic. This also contains caffeine, but unlike the shampoo and conditioner, you don’t wash it out.

Before the menopause, hair roots are protected by high levels of female hormones (estrogen). After the menopause, estrogen levels will decline and the impact of male hormones (testosterone) will increase.

Nature’s phyto active ingredients help the scalp protect itself from the consequences of decline estrogen levels. The caffeine in this shampoo prevents premature exhaustion of hair growth caused by the impacts of testosterone. Plantur partly bases their claim for caffeine on studies that show the hair follicles retain caffeine up to 24 hours after using the shampoo. They stop short of actually suggesting the shampoo can cause hair growth. And finally, some mention a combination of the above: less hair loss, and improved hair texture and appearance. You should leave both the shampoo and the conditioner on your scalp for at least two minutes each. This will allow for sufficient absorption of the caffeine and maximum penetration to the follicles. Having tried other shampoos for hair growth, and possibly minimizing hair falling out, I stumbled upon Plantur 39, I started using them and initially it felt good, as I like the smell, and it didnt seem like any harsh chemicals are inside this, so it was a thumbs up.
