Caffeine is known to help increase blood circulation to the scalp which promotes healthy hair follicles. When you're massaging hair products directly to the scalp you're aiding blood circulation to the scalp and stimulating the roots.
Caffeine, as a stimulant, improves blood circulation to hair follicles. This, too, can speed up and strengthen hair growth, giving it a fuller, thicker appearance.
Does caffeine shampoo work? It is unclear. Whilst the study above showed that caffeine does stimulate hair growth in a laboratory dish; there is not enough evidence to prove it works with hair on the scalp.
Caffeine has been found to block the effects of DHT, which may help to prevent hair loss. Improves scalp health: Topical caffeine can improve blood circulation in the scalp, which can provide essential nutrients to hair follicles and promote a healthy scalp.
Foods rich in lycopene such as tomatoes, watermelons, carrots, and mangoes naturally block DHT production. Biotin-rich foods like berries, liver, legumes, oily fish, and bananas condition the skin and scalp creating an overall healthy environment for strong hair.
It is promising to see that caffeine combined with other treatments, such as minoxidil, may achieve better results in hair growth. However, there is no clinical evidence that caffeine alone can achieve the same results as treatments such as minoxidil or finasteride.
Put simply, caffeine shampoo has the same effect on your hair as that triple shot cappuccino you used to order every morning on your way into the office: it helps to stimulate and energise the scalp in order to help encourage hair growth, while restoring hair follicles.
Although caffeine can help to promote hair growth, it is not a miracle worker and drinking a lot of coffee will not stop your hair loss. Hair loss can be caused by a number of different reasons and it is important to find out what is causing your hair loss to find an appropriate treatment.
If you're a coffee drinker, you've probably wondered whether caffeine causes hair loss. In the past, it was believed that caffeine could accelerate hair loss. However, recent studies suggest that there's no link between caffeine and hair loss.
Coffee powder brewed with coconut oil helps increase blood circulation in the scalp and stimulates hair growth.
In short, from the data we have, caffeine has a positive relationship with your hair health. There appear to be no studies linking caffeine to hair loss, and rather a nominal few suggesting a link between caffeine and better hair growth potential.
Let's clarify something from the outset – drinking coffee is not going to help your grow your hair. We would need an equivalent of 50-60 cups of coffee in order to produce noticeable hair-growing results – the amount which is unsafe and dangerous for your health, and is NOT what you should do.
After 120 hours, the caffeine-treated hair follicles grew longer hairs compared to the control. Depending on the caffeine concentration, they were between 33% to 39% longer.
Alpecin shampoo contains caffeine, which is said to stimulate hair growth. It also uses piroctone olamine to control dandruff. However, in certain cases, it may cause issues like hair thinning as well. This shampoo can only be used as a short-term treatment for hair loss.
What happens if I stop using Alpecin? The hair will return to its normal phase. It won't suddenly fall out but you will notice that your hair loss will gradually return to its normal rate.
Niacin, one of the B vitamins, promotes healthy blood flow to the scalp which keeps the follicles healthy and helps blocks DHT. This nutrient is also essential for other cosmetic purposes, such as aging and general health.
Talk to your doctor about finasteride.
You can get injections or take it in pill form. Finasteride acts on enzymes that concentrate in your hair follicles, inhibiting the production of DHT.
The most straightforward way of achieving this is through an oral 5-alpha-reductase (5αr) inhibitor. As the name suggests, these medications inhibit the 5αr enzyme which converts testosterone to DHT. Without a functioning enzyme, DHT levels in the blood plummet which is quickly reflected in the scalp.
DHT and PCOS
It happens when their ovaries create excess androgens, including testosterone, which leads to increased DHT levels. This causes a variety of symptoms, including irregular periods, excessive hair growth (hirsutism) and acne.
However, DHT blockers do not directly promote new hair growth. Instead, they are preventing your hair follicles from shrinking due to DHT. That can lead to the growth of new hairs depending on your stage of hair loss.
Getting a blood test is the most common way to establish your DHT levels, but a saliva panel test is considered more accurate. These tests are not generally available through your GP although your doctor should be able to point you in the direction of a specialist who can run these tests for you, privately.
