Promising review: "I’ve been using Dr. Groot’s for a while now, and I can honestly say it’s been a game changer for my hair and scalp health. From the first few washes, I noticed a difference — not just in how clean my hair felt, but in how balanced my scalp became. My hair feels stronger, softer, and noticeably healthier. I’ve also seen less breakage and shedding over time, which was a huge concern for me before purchasing. Overall, Dr. Groot’s Hair Care has exceeded my expectations. If you’re struggling with dryness, thinning, or just want healthier-looking hair, I would absolutely recommend giving it a try." —Amazon Customer

Promising review: "I've waited a while to write a review on this product, to give it sufficient time. I have had this on auto delivery for over a year now and can say that it has greatly helped with my hair loss, especially around my temples. It requires consistent use daily, as sometimes if I missed a week, I would notice, but the cost and time/effort are worth it. Will continue to keep on auto delivery." —Elizabeth

Promising review: "So, I'm picky about my hair. Wash-every-day kind of person. I hate the feeling of dry shampoo, and the weird texture it leaves, and your hair still looks oily? Hate that. This doesn't do that at all. Small amount of texture it leaves, but your hair will be MATTE. It's perfect. 10/10 recommend." —Kaitlyn

Promising reviews: "Legit magic in a bottle. Wish I could order this stuff by the gallon. Took a chance on this because I was desperate, having already spent so much money on luxury and drugstore products with little results. I use this as a pre-treatment on my scalp and ends before I wash my hair. Scalp has improved dramatically. I feel like there’s not as much breakage/fallout, and my ends are fuller. (This is after like six months, but my scalp was better immediately.)" —Claire Blanchard

"I hardly write reviews...but this one deserves to be written about!! My hair was falling out a LOT, and somehow, just with the FIRST application onwards, I started seeing less fall. And now, after four months, I can see hair growth as well, and my hair is already looking thicker!! And I’ve been using it only once a week. It's just a few drops and massaging in. Omg, how can anything be so simple and yet so effective!!! Amazing! Amazing!!! Whoever invented this...hats off!!" —Dee

Promising review: "This is my second bottle, and I absolutely love this product. It's a great way to cleanse my scalp and hair from the buildup of products during the week. It leaves your scalp clean and smelling fresh without stripping it. A great first step before following with the hydrating shampoo. Also, a little goes a long way." —Charlene P.

Promising review: "Yes, yes, yes!!! I’m a fan of Medicube skincare, so when the haircare line came out, I jumped on buying it. I LOVE this stuff. Immediately, my hair felt fuller, shinier, and I had way less breakage or hair falling out with brushing. I’ve also noticed that I can go an extra day or two between washings because it doesn't get as greasy as fast. Also, this conditioner smells SO good!!! I feel like I’ve had a spa treatment every time I wash my hair now. This is my new go-to!!!" —Christy May

Promising review: "I own a barbershop and use this as part of my hair and scalp treatments. This product works great, and my clients always say it feels amazing on their scalp. It leaves the scalp feeling refreshed, soothed, and clean without being harsh. Definitely one of my go-to products, and something I’ll keep using. Highly recommend!" —Steven S

Promising review: "I bought this to use on my scalp to help my Minoxidil hair regrowth treatment penetrate into my skin better. So far, I'm having very noticeable results, much more than before I started using the derma roller." —Wenda

The brand recommends using it every three to four days for up to eight weeks for the best results.

Promising review: "This shampoo really works! After just a few washes, I noticed a huge reduction in dandruff and itching. The 1% ketoconazole formula is strong enough to control flakes, but still gentle on the scalp. It lathers well, has a clean scent, and leaves my hair feeling fresh and nourished. I use it twice a week alongside my regular shampoo, and it keeps my scalp clear and comfortable." —Amin wakaly

Get it from Amazon for $15.88 (also available in a 2-in-1 shampoo + conditioner version).

Promising review: "I wear a lot of braids, and my edges came out with one particular setback in 2023, and they would not grow back no matter what I tried. I started using Cecred's Edge Drops for the past two months, and I am shook. The results are incredible. Will definitely keep this in my haircare regimen." —Jenny

Promising reviews: "I saw this little thing all over TikTok, and everyone swore by it. To be honest, they’re right and I now swear by it. It’s perfectly soft and sturdy to massage the scalp. Works shampoo into roots, helps with dry skin and such. I absolutely love it, and I use it every time I wash my hair. I most definitely would recommend it to anyone. Don’t hesitate." —Z

"I have suffered from dry scalp and dandruff for years. I recently shaved my head and realized just how bad my scalp really was: red, irritated spots everywhere became very easy to see with my short hair. After using this product along with a coconut oil moisturizer for three days, my scalp is already healing. The product is easy to hold, easy to clean, and feels great on an itchy scalp. I also don’t have dandruff flakes at all anymore. Trust me, you won’t regret purchasing this product!" —Britt

Get it from Amazon for $6.49+ (available in three colors).

Promising review: "Since I’ve started using this (consistently since January), I have had MANY people ask if I’m wearing my extensions! It has helped thicken my hair up WITHOUT drying it out. I use the shampoo and conditioner in combination with these drops. I LOVE the minty feel/smell it leaves my scalp with." —Chandler DesRochers

Locsanity is a Black-owned small biz that specializes in haircare products for dreadlocks!

Promising review: "Never used a deep cleanse before and went to the beach last month, which added a lot of sand build-up. I tried washing it out a few weeks ago, but the sand was too deep in my locs. This helped get most of it out. I felt relieved! I have freeform locs, and I will be purchasing this for another cleanse." —Ben

Get it from Amazon for $16.19+ (available in six scents).

Promising review: "Cannot recommend enough! Makes my hair and scalp feel so clean. After postpartum, my hair changed drastically and I could never get it clean. I was so upset and uncomfortable. This product literally saved my hair! Smells great, and it's easy to use. I only use it once a week, and it brings my hair back to life. Feels like I just left the salon!" —Thee Honey House

Get it from Amazon for $12+ (available in two sizes).

Don't use this if your wig, weave, or extensions were applied using any sort of adhesive!

Promising review: "I am surprised at how well this works. I used it to take down my braids, and it made it so much easier to comb through the buildup. I was also shocked at how easy it was to get my hair clean after finishing my takedown (the shampoo gets credit for that, too). Now that I'm in braids again, it's great for helping my scalp actually feel clean and refreshed after workouts and in between washes. This would be amazing for travel, so a mini would be amazing." —Lauren

Get it from Ulta or Cécred for $18+ (available in two sizes).

Promising review: "A little goes a long way. I was skeptical at first, but by far, this is one of the best dry shampoos I've tried. You really can't beat it at this price point. It leaves your hair shiny, soft, and smooth. The other dry shampoos I've tried always dulled my hair, and I could feel a powdery coating on my hair. Not this one! This leaves my hair feeling like I just washed it. It smells great, too. Would totally recommend! (For reference, I have thin, straight, highlighted hair that tends to get oily at the scalp quickly)." —Sarah Granillo-Ramirez

Promising review: "I’ve been using this rosemary root enhancer for a few weeks and really like how light and refreshing it feels on my scalp. The spray absorbs quickly, doesn’t feel greasy, and leaves my hair feeling clean and hydrated. I’ve noticed less shedding, and my scalp feels healthier overall. The rosemary scent is natural and not overpowering. It’s very easy to apply daily, and I appreciate the clean, plant-based formula. Hair growth takes time, but so far this product has helped improve scalp condition and made my hair feel stronger at the roots. I’m happy with it and would continue using it." —Shohida

Promising review: "This product is amazing. I was using a product called DermMatch, and I was going online to order some more when I came across this item. I used it for the first time after showering this morning, and decided to apply it onto my damp hair. That may not be how it is meant to be applied, but it worked so well. I did not comb my hair back prior to applying it, I just dabbed it onto wherever I could see my scalp, including my hairline, and it looked like it covered very well. The test was when I combed my hair back and styled it the way that I used to. It passed the test with flying colors. To top that off, it was waaay cheaper than the DermMatch. I very strongly recommend that anyone give this a try. I am absolutely blown away at how well it works for me, and I am very picky about my hair. Just try it!" —dd

Promising review: "Smells so good and is not overbearing at all. I've tried a lot on my locs and this is the best I've found in five years!" —Loe55

Promising review: "This salve moisturizes and soothes my scalp when it feels dry. It’s light enough to moisturize and seal my ends without weighing them down, and it gives a nice shine to my hair. The subtle vanilla-ish scent is very nice, and not overbearing." —T

Girl + Hair is a woman-owned small biz that specializes in products to maintain natural hair underneath hair extensions.

Promising review: "I have braids in. It's going on three months, and this product got rid of ALL my buildup — one wash!!! I also have scalp issues with flaking and itchiness because of the braided hair. This product got rid of flakes, itchiness, and buildup. Not to mention, the bottle is big and AFFORDABLE. Y'all, this is a WIN! I faced many struggles with other shampoos and my flaky scalp condition. WHEN I TELL YOU this scalp has been clean for a week now... Usually, the flakes come back after a week, but they haven't. I want the whole darn haircare line. FYI, Black-owned by a dermatologist!! Get on it.
