"Using the right shampoo consistently made a real difference — my scalp felt healthier within weeks and my hair started looking noticeably thicker."

An Ounce of Prevention

Are you okay with losing all your hair in 15 years' time?

Thinning hair progresses in a well-known pattern called the Norwood Scale. Although the rate of hair loss varies between people, the typical time-frame for someone to lose their hair is around 15 years.

Whatever stage you are at now, are you going to be happy in 2 or 3 years time when you reach the next stage if you do nothing? If nothing changes then your hair will get worse.

"But if you decide to do something now then in 6 months' time you can have more, thicker, healthier and stronger hair than you have today."

    Don’t expect a shampoo to magically regrow your hair – you need to incorporate other treatments/products etc in your routine to really notice a difference. Having said that I do feel like my scalp is a lot happier and the hairs feels more secure in my scalp, so i think it is working.

    I recently noticed that I was losing large handfuls of hair while shampooing, and my once thick hair was visibly thinning. After reading positive reviews, I decided to give this product a try—and it works! My hairdresser even pointed out that I have lots of tiny new hair growth, which was exactly what I needed to hear. I definitely give this product a thumbs up. However, I believe the trick is to leave both the shampoo and conditioner on your hair for at least 2 minutes each to get the best results.

    I was initially skeptical about whether this shampoo would deliver on its promises, but I’m pleasantly surprised—it really works! I’ve been using it for about three weeks now, and I’ve noticed significantly less hair fall. There’s much less hair coming out when I shower or brush my hair. The most noticeable change is that when I run my fingers through my hair during the day, I no longer experience the excessive shedding I used to. Now, only one or two strands fall out instead of the 20-30 strands I was losing before. I’m thrilled with the results so far and plan to keep using it. The bottle mentions that most people see major results around the 8-week mark, so I’m delighted to already see improvement at just three weeks in.

    I use this with Maxoxidil every day, dermaroller once a week and I’m seeing new growth around the temples which were previously thinning quite badly.

    Combine this shampoo and the hairguard scalp brush and you will notice a difference in how your scalp and hair feels. Mine used to be very dry and flaky, and now that’s completely cleared up. My hair feels thicker and I think the bald spot on my crown is filling in, although it’s difficult to tell for sure.
