Topical caffeine can cause skin irritation, especially for those with sensitive scalps. Some people report itching, redness, or rashes when applying caffeine-based products. As a stimulant, caffeine can increase scalp sensitivity, particularly if used in high concentrations or combined with other strong ingredients.
Short answer: Potentially. "Caffeine is a stimulant that increases circulation, allowing beneficial nutrients and oxygen to be delivered to the hair follicles to keep them healthy," explains Dr. Michele Green, a board-certified dermatologist in New York City.
In fact, research has shown that caffeine is absorbed through the hair follicles at a much faster rate than through the outer layer of the skin, with caffeine being detected in the bloodstream as little as 5 minutes after topical application (Otberg et al, 2007).
You can simply apply every night and then leave the product on to be absorbed by the scalp. HOW LONG DOES IT TAKE TO SEE RESULTS? You will see results from using the Caffeine Stimulating scalp treatment after using every night over a 3 month period.
After topical application, caffeine was already detected in the blood of the volunteers after 5 min, whereas, when the hair follicles were selectively blocked utilizing the newly developed Follicular Closing Technique (FCT), caffeine was detectable only after 20 min.
In this study, a caffeine-based topical 0.2% liquid was found to be no less effective than minoxidil 5% solution regarding the percentage change from baseline in AR at 6 months in both the PP population (primary end point) and ITT population, using frontal and occipital trichograms.

Description. The INKEY List Caffeine Stimulating Scalp Treatment is an overnight scalp treatment that uses caffeine powder and an ingredient called Redensyl™ to help reduce hair loss by stimulating the scalp and hair follicles, therefore encouraging hair growth and helping to improve hair thickness.
Studies have demonstrated that topical application of rosemary oil significantly increases hair count and thickness, while caffeine has been shown to prolong the anagen phase of the hair growth cycle, resulting in enhanced hair growth.
Studies on Hair Growth
The results showed that the stimulant did, in fact, help aid in hair growth, with even the hair treated with growth inhibitors showing improvement. It seems that the caffeine both stimulates the hair shaft and blocks the effects of growth inhibitors such as testosterone.
You can start by incorporating foods like green tea, saw palmetto, and pumpkin seeds into your diet, as they are believed to have properties that reduce DHT production. Additionally, managing stress and maintaining a healthy lifestyle can contribute to natural DHT reduction over time.
Alpecin shampoo works via the caffeine content penetrating through the hair shaft and scalp in order to stimulate and activate hair growth at the hair follicles. It also contains vitamin B3 and zinc, which help to keep the hair roots healthy.
It's not possible to reverse or treat gray hair. But, with advancing research, this may be an option in the future.

It is uncommon for Alpecin Caffeine Shampoo to cause harmful or lasting side effects.

Check the ingredients on the product packaging before use.
A biotin deficiency may lead to hair loss, and supplements may aid hair growth. However, evidence has not shown that biotin supplements can boost hair growth in those without a deficiency. Biotin is an essential B vitamin that helps the body get energy and nutrients from carbohydrates, proteins, and fats.
Here's the tea (get it?) on caffeine for skincare: it's what's called a vasoconstrictor, meaning it is known to make blood vessels smaller and tighter. These properties have an immediate effect in your body care. Caffeine helps reduce blood flow to the skin, so it appears visibly firmer.
Caffeinated skin care products are typically safe to use at any time, though if you're using them for temporary tightening, brightening and the like, it's best to use them in the morning because remember: As the product wears off, so too will its benefits.
Caffeine dilates blood vessels.
Caffeine is a vasodilator, meaning it opens blood vessels in the brain, allowing blood to flow more freely. Headaches result from constricting blood vessels in the brain. "That's one reason why medications designed to fight headaches contain caffeine," Dr. Moghaddam says.
