“I highly recommend this shampoo to people who have thinning hair. I noticed my hair did not shed as much, and my hair looks thicker. Since using Dr. Groot shampoo, I no longer need to use Toppik, which is a microfiber hair I sprinkle on my thinning hair to cover my bald spots. Dr. Groot is the most expensive shampoo I’ve ever purchased, but it is well worth the price. As much as I like the shampoo, it doesn’t have the nice fragrance that other shampoos have, but I’m okay with that.”

Most conditioners damage hair, directly thinning it because they leave a heavy residue that drags strands down. Dr. Groot’s Thickening Conditioner is designed to hydrate without weighing hair down. It is formulated with biotin and encapsulated prebiotics. It helps strengthen the root and completes the shampoo system, so you get a full treatment from cleanse to condition.
Customer Review (Verified Purchase)
“I really like this scalp conditioner! It smells great and feels amazing when applied. There’s a cool, refreshing sensation when massaging it into the scalp that makes it feel extra clean and soothing. Since it’s a scalp-focused conditioner rather than a traditional one, it leaves my scalp feeling fresh, balanced, and comfortable without weighing my hair down. My hair feels soft and looks healthier after using it. Just be sure to rinse it well for the best results. Overall, it’s a really nice addition to my hair care routine!”

Spray it on the hair and massage it in. Used once to several times a day, it keeps your scalp environment balanced and primed for healthy hair growth.
Customer Review From LG Beauty
“The Scalp Relief Tonic is very cooling and has a pleasant smell. I was hoping to use it to stretch out my hair washing days, as I currently wash every other day and use dry shampoo in between. I planned to apply the tonic the day after a wash day and then use dry shampoo the following day, but this product is more intended to be a scalp soother. I tend to have a more oily scalp, and this has a wonderful scent and adds a good amount of moisture to my scalp.”
