The Science: How Does Caffeine Work On Thinning Hair? 

Androgenetic alopecia (AGA) is a common, hereditary form of gradual hair loss, also known as female or male pattern baldness. It’s caused by the hormone dihydrotestosterone (DHT), which can have a negative impact on sensitive hair follicles. DHT doesn’t cause hair loss for everyone – this depends on the sensitivity of an individuals’ hair follicles to the hormone, which is different for everyone.

So, how can caffeine help combat AGA? Studies have found that caffeine can counteract the effects of testosterone on sensitive hair follicles, and can improve scalp and hair follicle health in men, leading to less hair loss.

Caffeine can also help promote hair shaft elongation for longer, wider hair roots in men, as well as prolonging follicles’ anagen phase (the growth phase of hair development). For women, it can have hair growth-promoting effects.

Caffeine Shampoo Vs. Minoxidil: What The Research Shows

Minoxidil is a topical medication applied directly to the scalp, approved by the FDA for the treatment of AGA in men and women. It’s available over the counter without a prescription.

Can you use caffeine shampoo alongside Minoxidil for thinning hair?

Yes, a combination of Minoxidil and caffeine shampoo can be used to maximize hair growth – one study found that using both in tandem increased hair count more than just Minoxidil. Discuss combination treatments with your healthcare provider before starting, especially if you take any other medications.

Who Should Try Caffeine Shampoo For Thinning Hair?

If you’ve noticed your hair looks or feels thinner, or is shedding more than usual, using a caffeine shampoo at this early stage can help slow the progression of hair loss. Studies carried out on its efficacy show that regular use can stimulate hair growth and reduce shedding.

You can build a regimen of different treatments and products to stop thinning hair, improve hair growth, and thicken your existing hair. We recommend pairing our caffeine-infused Hair Fall Defense Shampoo with one of our serums.
