In this review, we will briefly review the most famous caffeine shampoo – Alpecin Caffeine shampoo.

Studies about caffeine for hair growth

caffeine and hair loss

As far as we know, there are at least several studies on caffeine and its hair growth promoting effects.

In one study, researchers gathered male participants with androgenetic alopecia, the most common hair loss pattern appearing in both men and women.

They performed a biopsy of hair follicles from the participants’ scalp and cultivated them in an environment where the follicles were exposed to testosterone and caffeine.

The result reveals that when caffeine was present, it had stimulating effects to hair follicles, which led to hair growth.

Alpecin caffeine shampoo review

First, Alpecin has patented their shampoo formula. According to Alpecin’s official website, their main active ingredient, caffeine, helps penetrate the scalp and goes directly into hair follicles.

The company clearly states that in order to have the caffeine content have a direct result on the scalp, you need to leave the liquid for at least 120 seconds (2 minutes).

Alpecin is a reputable brand and their product looks promising.

However, I noticed SLS is listed as one of the ingredients, which is a big concern nowadays. If their focus is to make a quality hair growth product, harsh chemicals like SLS need to go.

Other caffeine shampoo to consider

Here is another recommendation if you are looking for caffeinated shampoo: Ultrax Labs Hair Surge Stimulating Shampoo.

The Hair Surge shampoo also includes caffeine as the main ingredient. Additionally, it contains saw palmetto (the ultimate natural DHT blocking herb) and Ketoconazole (FDA approved medical compound used for inhibiting fungal growth from the scalp).

Basically, Hair Surge Caffeine shampoo by Ultrax Labs is an advanced version of Alpecin. It  has thousands of positive customer reviews. Many users report that their hair look visibly thicker and a big help controlling excessive hair fallout. Similar to Alpecin, if you decide to try this shampoo, make sure you leave it on your scalp for 2 minutes for maximum caffeine absorption.
