An Occurrence Analysis of Ingredients Declared as Active in Anti-Hair Loss Products and Systematic Review of Studies on Their Effectiveness

A user is considering a hair loss treatment lotion containing minoxidil, adenosine, caffeine, melatonin, and azelaic acid, questioning the interaction between caffeine and adenosine receptors. Another user suggests adding a topical anti-DHT ingredient like spironolactone, noting it should not be taken orally by men.

A user is seeking suggestions for a custom hair lotion mix containing minoxidil, finasteride, caffeine, niacinamide, and biotin. Another user suggests adding tretinoin, topical valproate, and bimatoprost.

The user is using Minoxidil, vitamin D, zinc, biotin, collagen, and micro-needling for hair regrowth. Some users suggest biotin and collagen are ineffective and emphasize the need for a DHT blocker for lasting results.

The user used microneedling, zinc, vitamin D3, biotin, magnesium, saw palmetto, pumpkin seed oil, and a DHT-blocker shampoo with biotin for hair loss. They are considering adding minoxidil due to stagnation in progress.

A user started a hair loss treatment 6 weeks ago using oral finasteride, minoxidil, biotin, vitamins B5, B6, and C, along with a topical serum containing batana, rosemary, castor oils, rice water, and more biotin. They are hoping to see progress by June-July.

The solution contains minoxidil, finasteride, azelaic acid, caffeine, retinoic acid, and procapil. Users suggest minoxidil with tretinoin and a 5-alpha reductase inhibitor, while dismissing retinoic and azelaic acids as unnecessary.
