Great for Hair Growth & Shine!
I’ve been using the Biotin & Rosemary Shampoo for a few weeks now, and I’m really impressed with the results. My hair feels noticeably thicker, softer, and healthier after each wash. The rosemary scent is refreshing but not overpowering, and I love that it’s sulfate-free, so it doesn’t strip my hair’s natural oils.I’ve also noticed less shedding and my scalp feels much cleaner and more balanced. A little goes a long way, and it lathers nicely for a natural shampoo.Overall, this has become one of my new go-to shampoos for strengthening and promoting growth. Definitely recommend it if you’re dealing with thinning hair or just want a fuller, shinier look!

This Biotin and Rosemary shampoo is a refreshing choice for those dealing with thinning hair. The sulfate-free formula cleanses gently without stripping moisture, and the rosemary scent is a bonus. After just few days of use, my hair feels noticeably thicker at the root, showing less breakage. It provides a lightweight lift and improved texture, making it a strong contender for anyone seeking natural support for hair growth and volume

Amazing product
The Biotin Rosemary Shampoo is a refreshing and effective hair care option for those seeking stronger, fuller, and healthier hair. Infused with biotin, it helps promote hair growth and reduce breakage, while rosemary extract stimulates the scalp and adds a clean, herbal scent that feels invigorating.After a few weeks of consistent use, many users notice less hair fall and a smoother texture. The formula lathers well without leaving residue, and it’s gentle enough for regular use—even on color-treated hair.Overall, this shampoo is a great choice if you’re looking for a natural, nourishing boost for thinning or dull hair.

Nice scent, great ingredients, good for your hair.
This shampoo is Biotin infused and promotes hair growth, along with a wonderful refreshing scent of rosemary, aloe vera, ginger root and tea tree oil. You will get a rich lather, and your hair will be fuller and smell great to boot. There is no leftover residue, and you can use it regularly. Since I have been using it, I’ve noticed my hair does seem fuller and stronger. If you need a boost for your hair, along with a clean feeling scalp and a great smell, give this one a try.

Maybe it’s working?
I have significant hair loss while using Zepbound. I don’t know if the hair loss is directly related to the drug, rapid weight loss, decreased nutrition, or hormonal changes from weight loss. I have been using this shampoo for several weeks. I like the shampoo. A small amount provides great sudsing. I like the smell, rather like original Ivory soap. The smell is not noticeable once I rinse. It is not drying. I leave it on the scalp a couple minutes, then rinse and apply a toning conditioner. I have noticed less hair fall but I don’t know if it is from the shampoo or an increase in biotin and hair growth vitamins. I have noticed some baby hair coming in around the hair line. It is a small bottle but considering that I use such a small amount and get a lot of suds, I expect the bottle will last a long time. I have fine, chin length hair. I intend to keep using the product and see how things go.

Very good
This shampoo is very refreshing when showering, and it has a very natural and delicious scent. I have noticed that my hair is stronger and falls out less, and it also feels and looks healthier. I recommend it if you have sensitive hair and scalp, as I have not had any problems with irritation or dryness, only benefits.

Shampoo
This RootStim product has been one of the best purchases I’ve made for my hair care. From the very first applications, I noticed an improvement in the texture and a feeling of freshness on my scalp. Its formula with biotin, rosemary, aloe vera, ginger root, and tea tree oil feels very high quality and leaves my hair clean, light, and revitalized.What I love most is that it helps with both hair loss and thickening.

Great shampoo
This shampoo is so incredible. Due to being post-menopausal and dealing with thyroid issues, my once thick hair is no more. I have literally tried every shampoo and conditioner on the market for hair loss without success. I have been shampooing multiple times a week with the Biotin Rosemary Shampoo. My hair loss has been dramatically reduced. The biggest surprise is that I don’t have to use a conditioner. Shampoo rinses out completely and leaves my hair soft and easy to comb out. This is a big plus. Hair and scalp conditioners build up on the scalp and hair follicles and can contribute to hair loss. Shampoo has a light, pleasant scent and a little goes a long way. I have been using this shampoo for two months now.
