@doctor.nicolej: Medicube's new scalp serum is clever marketing, not a hair growth miracle. Their own ingredient list says the rosemary is 0.2 parts per billion and the PDRN is 100 parts per billion. That's basically nothing! The PDRN hair studies are injections, not a serum, and there are no studies showing EGF helps your hair grow when you put it on your scalp. The caffeine is the one ingredient here that might actually help. If you want a scalp serum, I like the Hair Restore serum from @neutrogenaukire @Neutrogena with peptides, niacinamide and caffeine, and alongside @Rogaine minoxidil it can be great for hair growth. Please stop spending your money on trendy ingredient lists 😭 #BlackTikTok #honestreview #4chair #hairgrowth #blackwomen

What do you recommend as a good shampoo/conditioner? The only PDRN I use is the 99% capsules, purely because they've been incredibly moisturizing for me, I agree it's EVERYWHERE with no studies 😭

Girl thanks for reviewing this. I bought into the hype and bought the shampoo, conditioner and serum set. I can’t say I’ve seen any difference.
