The symptoms may worsen if the shampoo also contains salicylic acid. If you have a sensitive scalp run a test on a small patch of skin to see if any adverse reactions take place. If you have dry and brittle strands this product may not be the best choice for you, as the active ingredient can dry out the hair.
Some users may also notice hair browning weeks after using a caffeine shampoo. That is why individuals with fair hair should be particularly careful before using it. In theory, yes, the caffeine contained in cosmetic products can be absorbed through the skin and increase the blood pressure. However, the amount of caffeine entering the body when applied topically is very small. Besides, you would have to leave the shampoo on your scalp for hours to receive as much stimulant as in a small cup of coffee.
They are applied for min only so they are safe to use for those with high blood pressure. More and more often you can find shampoos containing caffeine on the shop shelves. And no wonder, since a few studies managed to prove the efficacy of caffeine for hair growth and its other benefits for the hair and scalp. Nevertheless, it does not mean that you should buy one for yourself as soon as possible.
Hair loss is caused by various factors, so the right treatment for you will depend on the underlying cause of your thinning hair. You can add a caffeine shampoo to your hair routine to fortify the effects of other products or medications.
But you cannot rely only on it in an attempt to grow healthy and thick hair. Besides, cosmetic products cannot offer a long-term solution. Once you stop using them, you will notice that their benefits also cease to take place. If your case of hair loss is severe, you should consider more serious measures. You might need to opt for a treatment with medications if your hair loss is temporary. Hair transplants have also proved to be an effective solution , especially for those suffering from DHT-induced hair loss.

What are the causes of hair loss?

Studies of human hair follicles show that caffeine increases the amount of cell energy in them by acting against a protein called phosphodiesterase.
It has also been shown to increase the protein insulin-like growth factor 1 IGF1 , an important signalling molecule in promoting hair growth. More specifically, caffeine has been shown to potentially reverse the effects of dihydrotestosterone DHT , the main hormone involved in common balding.
Most men begin to notice thinning hair or a receding hairline in their 20s. But although male ha Currently, there is no clinically viable evidence that they have a long-lasting effect on male pattern baldness , which occurs in men who have a sensitivity to DHT, and causes hair follicles in the scalp to weaken and shrink. Caffeine shampoo has not been proven to negate the effects of DHT in the long term. In , the UK Advertising Standards Authority ruled that caffeine shampoo Alpecin must no longer advertise that it can "help to reduce hair loss" as there was no adequate evidence to support the claim.
The German brand was established following a study in showing that caffeine caused hair follicles to regrow in a laboratory dish, but there is not enough evidence to prove that caffeine works with hair on the scalp. The caffeine molecule penetrates easily into the hair follicles but it remains questionable as to whether a sufficient concentration of caffeine can be delivered via a shampoo to maximise its potential benefits.
The growth-enhancing effects of caffeine are likely to be greater with leave-on topical caffeine solutions, Wong suggests. Or so were the claims of Alpecin: a German shampoo company first established in that uses the supposed powers of a morning cup of joe to rejuvenate men's hair.
According to research conducted by the company's parent group, Dr Wolff, Alpecin and other similar caffeine shampoos work by dousing hair follicles in caffeine. From there, it penetrates the skin to stimulate growth and counter the not-so-great side effects of testosterone, which, in some men, causes the release of a byproduct called dihydrotestosterone DHT.
That's the stuff that shrinks hair follicles and stops them growing new hair. A post shared by Dr. Sounds great. But the efficacy of this treatment has come under question by leading experts, and Dr Wolff's findings have not always been corroborated elsewhere. Other treatments include microneedling, low level light therapy, or a more targeted therapy depending upon whether the patient is male or female, and the grade of the alopecia diagnosed.
Just that they work better in a petri dish than in your shower. But again, the jury is out — as is the Advertising Standards Authority. In , the UK regulatory body ruled that Alpecin was no longer allowed to state that it could reduce hair loss, with a spokesperson stating that "we considered that we had no seen any studies of the actual product as used by consumers on their scalp using an accurate and objective analysis of hair growth, in a well-designed and well-conducted trial.
It's high time we all woke up and smelt the coffee. Verdict: Sorry guys.
