What our customers are saying
I was so impressed with the sample that I purchased the full product. It lathers up nicely and rinses off easily. It seems to dry my hair in less time, even when I use a hair dryer. I've been struggling with frizz due to aging, but it's been significantly reduced and my hair is now moisturized and manageable, so I'm very satisfied. Why did I give it a -1 star rating? The scent is sweet, and I feel like I've smelled it somewhere before. Ah, that's right! It's the scent of L*S*H's Mi*bachi March...! The scent is quite strong. I found the strong scent overwhelming, so I gave it a -1 star rating. The scent didn't seem as strong in the sample, but maybe I was so impressed with the experience that it didn't bother me? If you can ignore the scent, I really like the experience, so I'll probably buy it again. I highly recommend it to anyone who is concerned about frizz and enjoys the scent of Mi*bachi March.
I recently entered Suzykirei's giveaway and won. It arrived on Christmas Day last year. It was a wonderful gift, reminding me to take better care of my hair, especially since I've been feeling unlucky lately and my hair has been getting a lot of fluff from being so busy at work. Thank you. I've been using the shampoo and conditioner for about a month now, and here are my impressions. First of all, the gorgeous, sweet scent is striking, and as someone who enjoys the scent of cosmetics, I'm pleased with it. Some people may find it too strong, but the scent lasts only after washing and fades away after a while. (Others have said it only has a faint scent.) While individual perceptions vary, I can't generalize, so I recommend it for those who enjoy a pleasant fragrance. The foam rinses off easily, leaving my hair smooth and moisturized after washing. I feel like I'm experiencing less breakage, and it really improves the texture of my straight hair. This has inspired me to try other ReFa hair care products. I currently have a straight bob, and I plan to continue using this product if I keep using it. Thank you for giving me this valuable experience.
I like the pink line of ReFa shampoo, so I bought this one thinking it would be more suitable for my age. The bottle is cute. It makes me excited. I don't think it needs a handle. The shampoo lathers well, and the treatment leaves a smooth finish when applied. It leaves my hair feeling silky smooth without being too heavy. The scent is a matter of personal preference, but it's sweet and strong. I found it to be within my tolerance range. I've gotten used to it. (lol) I like it so much that I plan to refill it and buy it again.
