  • Amazing shampoo and conditioner
This shampoo and conditioner is very expensive but worth every penny. It works! It changes your hair from drying damaged to full and healthy.

  • Good product
I’ve been using for about 6 months and I do feel my hair is growing better. I don’t see a drastic difference yet as it takes time but my hair does feel healthy and longer.

  • Monat is the best thing I have purchased on AMAZON
I’ve been using MONAT for over six months now, and the results have been incredible. My hair was previously dry, frizzy, and thinning—but after switching to MONAT’s shampoo, conditioner, and Rejuveniqe Oil, my hair has never felt healthier. what i love most is: Noticeable hair growth and thickness after consistent use. Products are vegan, cruelty-free, and free from harsh chemicals like sulfates and parabens. The Rejuveniqe Oil is a game-changer—great for both hair and scalp My scalp feels balanced and less oily between washes. love this product you wont be sorry ... show more

  • Would not recommend. See pics
I wanted to love it but instead it just made my hair fall out. I used it according to the label instructions and decided after 9 washes I better stop or I would be bald. I’m 49, maybe it is better for younger people? I’m returning it tomorrow. My hair was thicker before using this product.look at the before pic on 7/8 vs 8/6 after using it for a couple of weeks… horrible product ... show more

  • I highly recommend
I have tried every growth shampoo and serum this is the first one that has actually cut down my hair loss by a little over than half when I am in the shower. I am 55 and have been dealing with hormonal hair loss . The massive clumps of hair that I was loosing in the shower was bigger than my palm and dense . But now I feel like it’s almost back to a normal amount I have been using it for a few weeks now ... show more

  • A Game Changer for My Hair
Since I started using the MONAT IR Clinical System, my hair care experience has changed dramatically. The complete kit, which includes shampoo, conditioner, and serum, has transformed my routine. I've noticed my hair feels stronger and healthier. The shampoo cleanses without stripping moisture, while the conditioner leaves my hair soft and manageable. The serum is the final touch; I've seen a noticeable reduction in hair loss and an increase in volume. This system has definitely exceeded my expectations, and I would recommend it to anyone looking to improve their hair health. ... show more
