FAQ

Rosemary extract increases blood flow to your scalp. More circulation means hair follicles get better access to nutrients. Biotin (vitamin B7) works on keratin production, reinforcing the structure of each strand so it's less likely to break when you brush or style. Hydrolyzed quinoa is a complete protein with all nine amino acids, so it's repairing existing damage while protecting fine strands from future breakage. The peppermint oil stimulates blood flow too, and it gives your scalp that cooling, tingly feeling when you wash. Clinical testing backs this up: hair becomes 3× stronger after one use, breakage drops by 70%. These key ingredients aren't padding. They're working.

Daily washing works for most people. The formula cleans without being harsh, important when hair's breaking easily. Some prefer every other day if their hair runs very dry. Personal call. The peppermint gives that tingly feeling on your scalp. Wakes things up. Can feel intense if you have a sensitive scalp, so it's better to start conservatively especially if it's your first time with this kind of formula. This isn't like those volumizing liquid shampoos that strip everything out and leave your hair squeaky. Pair it with a conditioner bar. The shampoo does the strengthening work, the conditioner handles moisture for your specific hair type.

It addresses scalp health, not the hormones themselves. Postpartum shedding, thyroid issues, menopause—those are internal problems no shampoo bar can solve. What this does is stop the hair you still have from breaking. When you're already losing more than usual, breakage makes things look dramatically worse. This formula strengthens individual strands and cuts breakage by 70%, so you're keeping more of what's growing. The rosemary and biotin improve scalp health and support new hair growth over time. Sudden or severe hair loss? Talk to a doctor. Could be something else going on that needs medical attention. Use this as part of your hair care routine. Not the entire solution. It helps, but it's one piece.

Dry storage is key. The bar needs to dry between uses or it'll dissolve too quickly. Any shampoo bar sitting in water or on a wet ledge dissolves faster. Use something with drainage—a dish with slots, a soap saver bag, a tin with ventilation holes. After washing, put the bar somewhere it can dry completely before you use it again. Traveling? Let it dry all the way before you pack it, or it turns into mush in your bag. Your first bar will probably surprise you—stored properly, it lasts as long as three bottles of bottled shampoo. Maybe 80 washes depending on hair length. Toss it in the shower and leave it in a puddle? You'll burn through it fast. Small effort, noticeable difference.

    Smells good, feels better

    I’m so excited for this shampoo. I have been using the curly hair shampoo and conditioner bars for years, but I’ve noticed lately that my hair is thinning. I can tell after just three uses that I have less hair coming out in my comb. In combination with the smoothing conditioner bar, my curly hair is still soft and smooth. I plan to alternate the two shampoos.
