    Hair loss is caused by many factors, including genetic factors, infections, hormones, and some hair products. Early studies in CBD caffeine shampoo see potential in the product, claiming that it can stimulate hair growth by fighting inflammation in the scalp and suppressing DHT deposition in the hair follicles.

    CBD caffeine shampoo is a relatively new product, but early studies suggest that it can stimulate hair growth. The ingredients in the shampoo, particularly CBD and caffeine, are responsible for this response. However, more studies are needed to prove these hair-related benefits. Early research showed that CBD can fight inflammation in the scalp, boosting its condition and that caffeine can suppress DHT, a testosterone hormone version that causes hair loss in men and post-menopausal women. Here is all you need to know about the ability of CBD caffeine shampoo to promote hair growth.

    The Basics of CBD and Caffeine

    According to Massi et al. (2006) and Bauer et al. (2020), CBD is a non-psychoactive chemical compound in cannabis plants like hemp and marijuana. Such chemical compounds are called cannabinoids, which are more than 140. Still, unlike THC, which, according to Schlienz et al. (2018), is intoxicating, CBD does not cause the 'high' effect. For this, CBD is gaining popularity and can be found in various products, from supplements to foodstuff.

    Caffeine is also a chemical compound in coffee or coffee beans. It is also found in cocoa, kola, yerba mate, and more than 60 other plants. As you drink tea or coffee, you are taking in the natural caffeine into your system. Besides being a central nervous system stimulant, caffeine is now becoming a central part of the hair industry. Together with CBD, they make up the CBD caffeine hair shampoo, which many people are running to solve their hair issues and stimulate their hair growth. How well does CBD caffeine measure up for stimulating hair growth? Here is what studies say.

    Do CBD and Caffeine Infiltrate Through the Hair?

    For CBD caffeine hair shampoo to offer any hair benefits, individual ingredients should be absorbed into the body. How do CBD and caffeine perform in this regard? Otberg et al. (2007) conducted a lab experiment in which blood samples were tested for caffeine, after applying caffeine shampoo on hair and leaving it open or covering it with a varnish-wax mixture and washing it off after 2 minutes. The closed and covered hair specimens resulted in positive tests for caffeine in blood samples, one 5 minutes and the other 30 minutes after application. This showed that caffeine can enter the bloodstream through hair.

    Caffeine Can Suppress Alopecia

    Alopecia refers to any type of hair loss. It occurs because of many reasons, including hormonal imbalance. Most men past 50 years suffer from androgenic alopecia (AGA), caused by the concentration of DHT hormones in hair follicles. As women go into menopause, DHT levels also increase, heightening the risk of alopecia. Does caffeine have anything to do with this? According to Bansal et al. (2012), caffeine is a better suppressant of alopecia. It can reduce the DHT concentration, allowing hair growth since the hair follicles are widened and freed.

    Caffeine May Help Lengthen Your Hair Shafts and Strands, Promoting Hair Growth

    Hair growth results from the lengthening of strands and shafts. According to Fischer et al. (2007), caffeine can promote the growth of hair follicles. Although the experience happened in a lab environment and did not use human beings, it revealed potential in caffeine CBD shampoo boosting hair growth. Later, Fischer et al. (2014) reported that caffeine could lengthen hair shafts and widen hair routes, stimulating hair growth. All these study findings sound promising, but more research is needed to provide sufficient evidence that caffeine helps with hair growth.

    Does CBD Have Anything to Do with Hair Growth?

    According to Gupta & Talukder (2021), CBD can fight skin conditions like eczema that extends to hair and causes its loss. The study also noted that CBD can promote hair growth by moistening the strands and offering the ideal conditions for hair growth.

    CBD in Shampoo: Can CBD Caffeine Improve Scalp Conditions

    A dry scalp is one reason your hair will not grow no matter what you do, and if it does, it will stagnate at some point. According to Nel et al. (2021), CBD can fight inflammation in the scalp. Without inflammation and drying, your scalp allows easy hair growth. Still, more studies are needed to prove that the percentages of CBD in the CBD caffeine shampoo can boost scalp conditions to favor hair growth.

    Should You Use CBD Caffeine Shampoo for Your Hair, And Will It Work for You?

    The products you use for your hair are a personal choice. Still, it is worth noting that genetic variations and their effects on hair are real. It is no wonder that conducting the effectiveness of certain hair products is difficult since people have different hair types and the products they have gotten their hair used to are also diverse. Therefore, if you choose CBD caffeine shampoo for your hair, that's fine. Still, remember that it might not necessarily work for you because of your hair or scalp conditions or other inherent factors.


    CBD caffeine shampoo is a product that many have incorporated into their hair. Early studies show that CBD can fight inflammation and boost scalp conditions, stimulating hair growth. Besides, preliminary studies on caffeine for hair growth show that the compound can suppress DHT, a testosterone version that causes AGA-related hair loss. These study findings sound promising and see potential in CBD caffeine shampoo, but because of insufficient scientific evidence, we don’t recommend the shampoo for stimulating hair growth.
