As it says it contains beauty serum ingredients, after washing my skin feels smooth and moisturized, and the scent is refreshing, so I love using it!
I purchased the set that came with the brush. The shampoo lathers well and leaves hair smooth. It contains beauty ingredients, but it's not sticky and has a light finish. It also has a refreshing scent, so it's a shampoo I especially recommend for summer.
It lathers well and rinses off easily. - My hair is manageable even after just shampooing. - I have slightly curly hair that tends to get frizzy on the surface, but this product is moisturizing but not too heavy and doesn't cause frizz. If I use a full treatment, it might be a little oily, but in the summer, my hair sometimes struggles to dry. It's not a problem in cooler months. I also love the refreshing, not-too-sweet scent that makes me want to use it every day!
I prefer a smooth, moisturizing shampoo. It lathers well and keeps my hair in place even after drying, which is great. Stella Seed shampoo is consistently high quality. The scent isn't too strong, but it's a floral one, so I think it's a scent that everyone will enjoy. The included shampoo brush was a bit stiff, but people who like hard brushes might like it.
I've been using this for about two weeks. The packaging is simple and stylish, so I bought it to try it out. I think it's a shampoo that lathers very well. I have thin hair, so I don't like shampoos that are too moisturizing, but this one was just the right amount of moisturizing without being too moisturizing. The only downside is that the shampoo pump is hard, so even when you want a small amount, it comes out in a big gush, which means you end up using a lot.
