Caffeine For Hair Growth


What Causes Hair Loss?

Before we begin, let’s discuss the causes of hair loss. This better helps us understand the issue and how we can rectify the issue. There are many causes of hair loss. For example heredity/genetics, illness/disease, stress and fatigue, exposure to harmful substances, medications etc.

In some cases, hair never grows back. In other cases they normally do. The third situation is being in the middle where hair regrowth needs external help.

There are medications for blood pressure, anxiety and birth control that can cause hair loss. The list is long but the point is if your medicines cause hair loss then stop using them. Talk to a doctor and seek safer alternatives.

Genetics is the biggest reason for hair loss in men and women. The type of hair loss that is mostly permanent. Hereditary hair loss is termed as androgenic alopecia. This male/female pattern hair loss is caused by hormones and androgenic activity in the body.

Hair follicles and receptors that are sensitive to the effects of DHT shrink. This means the hair they are holding on to will most likely fall off. Over time a lot of hair follicles shrink and the person becomes bald. In the case of women, there is thinning that exposes the scalp. And because of this, no new hair growth.

Does Caffeine Cause Hair Loss?

No one knows where the rumor started. Probably someone who did not want their kids drinking coffee. Anyways, this is most definitely not true.

Drinking excess coffee does cause accelerated heart rate, urination, mania, and hyperactivity. But hair loss is not on this list, trust us on this one. A lot of drinks we enjoy so much have caffeine in them.

Drinks like sodas, carbonated drinks, energy drinks, and iced tea/coffee etc. There are a lot of studies, supported by clinical and scientific evidence that caffeine is very good for hair growth.

Benefits of Caffeine for Hair

In a clinical trial, hair samples were taken from the vertex area of a volunteer’s head. Those hair were cultured in incubation for 120-200 hours. Their rate of growth was observed and measured every day.

Then the hair was exposed to 5 microgram/ml concentration of testosterone. This resulted in the suspension of growth in hair strands.

To counter the effects of testosterone, hair was given 0.001% – 0.005% concentration of caffeine. It was observed that exposure to caffeine actually made hair grow. Slightly increasing the concentration proportionally increased the growth rate of hair.

To conclude, caffeine had a positive effect on hair growth. And it can be very beneficial for those who have hair loss from heredity. As permanent as hair loss may seem, if caught and treated at an early stage, it is treatable.

How does Caffeine Grow Hair?

DHT is the real enemy here. We mentioned in our other articles that it is the major cause of hair loss in men and women. Caffeine directly targets the DHT in the body.

Like other parts of the body, hair needs nutrients to stay alive and keep growing. DHT molecules attach themselves to these follicles and cut off the nutrient supply. This causing follicle to shrink and make hair fall off.

Caffeine will make hair cells produce more adenosine triphosphate (ATP). This is the basic energy source of the cells, that keep them in an active growing phase. Hair follicles shrink and die because of exposure to DHT.

Will Drinking Coffee Make Hair Grow?

Scientists believe that drinking/consuming/applying caffeine can help hair grow. There are hair care products that contain caffeine which is specifically formulated to promote hair growth and reverse hair loss in men and women. These products make hair thicker, fuller, and healthier.

But caffeine is not a miracle worker. There is no 100% guarantee that drinking a large quantity of coffee or applying a lot of caffeine-infused shampoos and conditioners will make a bald person grow hair.

Address the root cause of hair loss. Consult your doctor and discuss your hair loss symptoms and concerns. So that they can perform the right tests to deduce an accurate diagnosis.

Does Caffeine Absorb Directly into the Scalp?

Study on caffeine absorption was done by researchers in different European countries. Volunteers involved Caucasian men, the subjects were asked to participate in 2 separate studies that were conducted at a weeks gap.

In experiment 1, the men were asked to apply a shampoo with 1% concentration of caffeine. The caffeine-infused shampoo was applied to a test area on the chest. Hair follicles were left exposed.

After a week passed, they were asked to apply the same caffeine shampoo, with the same 1% concentration on the chest. But this time the hair follicles were then closed with a mixture of organic wax.

All the men had their caffeine levels checked via blood test before they participated in the experiments. The shampoo was cleaned after two minutes and blood was taken at 5, 10, 20, and 30 minutes as well as 1, 2, 5, 8, 24, and 72 hours after the shampoo was applied.

Men in the first group had caffeine in their blood that was detectable just five minutes after the caffeine shampoo was applied. The actual concentration found was 6.3 ng per milliliter.

For the second group, it took 6 times longer for the caffeine to be traced in the blood. It took half an hour versus 5 minutes with the first group, which had the follicles exposed.

The study concluded that having the follicles closed off in the second group made the caffeine absorption far more difficult. Hence, when caffeine is exposed to hair follicles it is able to be quickly absorbed into the scalp.

For this reason, using caffeine-infused shampoos and conditioners is a quick, easy, and effective way for hair growth stimulating caffeine to be absorbed into the area where it is needed most; the scalp.
