Best product I have used so far!
Style: Shampoo, Size: 7 Ounce
I’ve struggled with dandruff for a while and have tried a few different shampoos, but this one actually made a noticeable difference fast. After the second use, I could already see that my flakes were significantly reduced and my scalp felt a lot less itchy. The shampoo lathers well and you don’t need a lot of product. I left it on my scalp for a few minutes before rinsing, and that seemed to help with the results. The scent is clean and not too strong, which I like. My hair didn’t feel overly dry afterward, which is something I’ve experienced with other anti-dandruff shampoos. So far, it’s been effective and I’ll definitely keep using it. If you’re dealing with dandruff and want something that works quickly, this is worth trying.

Clean Ingredients. Love this fragrance! Clean, light and refreshing.
Scent: Rain Water, Size: 33 Fl Oz (Pack of 1), Scent: Rain Water, Size: 33 Fl Oz (Pack of 1)
I absolutely love this brand of hand soap. One of the biggest things that stands out to me is that it’s made with natural ingredients, which makes it feel like a much cleaner product compared to others I’ve used. The fragrances are all amazing, and I really like that they use essential oils instead of harsh synthetic scents. It smells great without being overwhelming. This fragrance is one of my favorites. I find myself coming back to it because of the light, clean & refreshing fragrance. It also lathers really nicely, and a little bit goes a long way, which makes it last longer than I expected. Overall, it feels high quality, gentle, and refreshing to use every day.

Great Product
Scent: Rain Water, Size: 33 Fl Oz (Pack of 1)
I just picked up this Liquid Hand Soap Refill in the Rainwater scent, and I’m seriously obsessed. I finally decided to stop buying those small plastic pumps every two weeks and grab the big 33 oz bottle instead. The Scent is Everything: If you like things that smell "clean" but not like bleach or fake lemons, you need this. It’s super fresh and garden-inspired—it literally smells like a rainy morning. Eco-Friendly & Saves Money: This one jug refills my countertop bottle about 2.5 times. It’s way cheaper in the long run and cuts down on all that plastic waste. Actually Moisturizing: My hands usually get so dry from washing them a million times a day, but this has aloe vera and olive oil in it. It feels really soft and doesn't leave my skin feeling tight. Clean Ingredients: It’s 98% plant-derived and cruelty-free, so I feel a lot better about having it at the kitchen sink where the whole family uses it. Honestly, if you're looking for a small way to upgrade your kitchen or bathroom vibe, this is it. It makes a boring chore feel a little more like a spa moment!

Like Mrs. Meyers Hand Soap
Scent: Basil, Size: 33 Fl Oz (Pack of 1)
Great hand soap and consistently re-purchase for use. Only downside has been the fluctuations in price. The fragrance is good and not over powering. Good at both greasy and non-greasy hand cleaning. Overall feels good on the skin!

Switched to Meyers, Not animal tested product
Scent: Lemon Verbena, Size: 33 Fl Oz (Pack of 1)
I love this refill and the smell is lemony and a sweet clean scent. I LOVE the fact this company does NOT test on animals and its good for the environment. I have switched to all Meyer products now including their room spray. It lathers nicely and it is gentle enough for my sensitive hands. I break out and dry out due to my autoimmune. I feel clean and this has been a great product. I was turned on to their body and cleaning products for when an AirnB home used it for all of their needs. I love seeing this in the larger bottles for refills. Great product!
