Soooo good!

"This treatment REALLY WORKS! however, you must remember a couple of things: a watched pot never boils, so FOLLOW the directions & BE PATIENT. I've looked up all kinds of similar serums, treatments & shampoos for hair growth from all kinds of brands & companies, & every one of them says you can't expect to see noticeable results for at least 90 days or even up to 9 months. I had a stressful event happen that caused my nails to turn weak as paper & I could suddenly see through to my scalp for the 1st time- it was scary. So I started *THIS* serum only & I have absolutely seen wonderful results. Make sure you use a few drops every day where its most noticeable, but rub the drops INTO YOUR SCALP, don't focus on your hair. . . . & even take a photo on your start date then take another photo 3 months later of the same spot where you treat it- mine are covered up, it's amazing. And I'm 51. Have had great hair my whole life. And this is light in texture & scent. Just lovely! When it gets to the end of the bottle & the dropper can't reach remaining serum, you could just find a bigger tincture dropper OR, like me, tip the bottle over & rub it in with your fingers. 🤷🏼‍♀️ Anyways, I love this product but didn't want to wrote a review til I definitely had let enough time go by- its been about 90 days, maybe a bit over-like I said, keep busy, don't stare at it, just check in at 60 days or 90 & see what's happening! FWIW, my hair is platinum bleached blonde for the past 25+ yrs or so & it's straight ish but has some wave, too. Hope this helps!"
