[This review was collected as part of a promotion.] Rule Cosmeceuticals Hair Growth Shampoo smells wonderful. It has a clean, earthy scent. It is a gray reducing, anti-dandruff and volume boosting formula. I like that it helps to prevent split ends and reduces breakage by 30%. It is infused with natural ingredients, such as, Ginkgo Biloba, Ivy, Saw Palmetto and Ginseng. I hope with continued use I will see more volume and less breakage.

[This review was collected as part of a promotion.] After using Rule Cosmeceuticals' Hair Growth Shampoo for a few weeks, I have to say I'm genuinely impressed. The first thing that struck me was the bottle itself; it has a sleek, minimalist, and almost clinical aesthetic that feels very modern and high-end sitting in my shower. It looks more like a product from a chic skincare line than a traditional shampoo, which I really appreciate. As for the performance, I've noticed my hair feels cleaner for longer and there seems to be less shedding in the drain, which is a huge plus. The lather is rich and it has a subtle, clean scent that isn't overpowering. My only real critique is that my hair can feel a bit tangled after washing, which leads me to my main wish: I truly wish I had the matching conditioner to go with it. I feel like the system is incomplete, and having that companion product would likely elevate the entire experience, making detangling easier and potentially boosting the hair growth results. Overall, it's a sophisticated and effective shampoo that has me hoping a conditioner is in the works.

[This review was collected as part of a promotion.] I recently added this No.10 Hair Growth Shampoo from Rule Cosmeceuticals into my wash-day lineup, and I’m pleasantly surprised by how much it delivers. First off, the concept caught me: a formula that’s designed to support hair growth and scalp health rather than just a regular cleanser. The texture is a nice middle ground—it lathers well without feeling overly stripping, and the scent is light and clean (no heavy perfume that lingers all day). After a few weeks of consistent use, I’ve noticed my scalp feels healthier (less tight, fewer little flaky spots) and my hair seems a little fuller around the roots—not dramatic overnight, but enough to make me keep reaching for it. One of the things I appreciate is that it doesn’t make my hair feel crunchy or coated; it still behaves like normal hair post-wash, which means I can style it as usual. On the flip side, it is an investment—this kind of performance comes with a higher price tag than a basic shampoo. And if you’re hoping for instant “thick mane” results, keep expectations realistic: hair growth and thickness take time, and a shampoo alone won’t replace broader hair-health habits. Overall, if you’re dealing with mild thinning, scalp issues, or you just want a smarter shampoo that goes beyond basic cleansing, I’d say this is a solid pick. For me, it feels worth it because I’m enjoying the process of using it (which is often half the battle) and I feel good about giving my hair a little extra care.

[This review was collected as part of a promotion.] I am really happy with this shampoo! I love that it does so much: makes hair grow faster, reduces grays, and is anti-dandruff. SO much in one product! The bottle is interesting. It reminds me of a shaving can and it squirts out the shampoo. (See video)

[This review was collected as part of a promotion.] The package is very beautiful! It is heavy. The smells is good and product leave hair very soft and shiny. After finishing treatment I came back to update about my hair growth. For now, it is a 5/5 for me.

[This review was collected as part of a promotion.] This shampoo is designed to promote a healthier scalp and encourage hair growth. Designed for both men and women this shampoo labels itself as a gentle anti-dandruff, hair growth shampoo. It’s packed with great ingredients that promote a healthier scalp which may help hair growth. Unfortunately it also has a very strong scent that I found too masculine for my liking. While my hair felt great after use, the scent linger so I can’t see myself continuing use. My husband agreed and felt the scent is better suited for a cologne.
