The gorgeous Milan recently sent me a request for information on tea rinses specifically with tea with caffeine. The forum world is buzzing about the magic of caffeine with everything from shedding to shine to hair growth. So, caffeine is Fridays food for thought!

I have seen that one particular paper has attracted a lot of interest because many people say that it proves that caffeine can increase hair growth (International Journal of Dermatology, pg 27-35, 2007).

Well here are the facts..

1. People taking part in the study
Males suffering from hair loss related to testosterone imbalance

2. How the study was carried out

OK this part will hurt to read. Hair follicles (the root of the hair) were extracted from the male patients (meaning a tiny bit of scalp and skin). These follicles were then treated with caffeine in the lab (not directly on the patient).

3. Why caffeine and why these patients?

Caffeine is thought to stimulate cell metabolism which could mean the cell can grow in size and possibly multiply in number. The rationale behind this study is that males suffering from this type of hair loss would have smaller follicles as a result and caffeine could stimulate the follicles to increase in size or number.

4. The result of the study
Yes caffeine did stimulate growth of the follicles in vitro (i.e in the petri dish)

5. The result for you
Be careful how you interpret this paper. The entire experiment took place in a lab not on a person's head. Also, the hair tested was that of people experiencing hair loss.

My view - I would really suspect that the effectiveness of this on a person is limited because surely if it was as simple as applying some caffeine to hair then we would have a hoard of men pouring (cold) coffee onto their heads and proclaiming to have a cure for baldness (if you think it needs curing!).


I have not come across any research relating caffeine to hair in any substantial way (except for the fact that it can actually be stored in the follicle and can also enter the blood stream though hair and ski,riveting for me, maybe not for all), but if you have and want me to check it out, let me know!

I also have included Natural vitamins and herbal remedies as well.

1. Ginkyo biloba - this popular herb is thought to improve blood circulation to the brain and skin. Herbalists believe that the increased flow of blood to the brain area delivers more nutrients to the hair follicle thus promoting hair regrowth. The recommended dose is 120-160mg of dry extract each day spread over three doses.

2. Green tea (Camellia sinesis) - it is thought that catechins found in green tea may inhibit the enzyme 5-alpha-reductase that converts testosterone into hair-unfriendly DHT. It is therefore believed to be effective in preventing and treating male pattern type baldness. You should drink several cups of green tea each day or take it in capsule form as instructed by the manufacturer.

3. He Shou Wu (Polygonum multiflorum) - also known as Fo-Ti, this Chinese herb has traditionally been used to reduce hair loss. It is found in many commercial preparations, or in tea and capsule form.

4. Pygeum (Pygeum africanum) - derived from the bark of an evergreen, it works in a similar way to green tea. It is widely used to treat prostate problems and male pattern baldness. Users should take 60-500mg per day in pill or capsule form.

5. Saw palmetto (Seranoa repens) - this is the current treatment of choice for many men due to its ability to protect the prostate, slow hair loss and encourage hair regrowth. It forms the core element of many commercially prepared hair loss treatments but can easily be obtained in its pure form. The recommended dose is a 160mg capsule twice each day, but make sure the ingredients are made from the berry extract not the dried berries themselves.

6. Stinging nettle (Urtica diocia) - this has long been favored as a means of preventing hair loss due to its ability to block the conversion of testosterone into DHT. It can be taken in pill or capsule form with an optimum dose of 50-100mg per day. It is particularly effective when combined with pygeum and saw palmetto.
