I've noticed a clear difference in my hair. It's so much softer, feels healthier, and slightly thicker without feeling weighed down. Plus, it smells amazing and leaves my hair feeling so clean. Hopefully, the effectiveness will continue, and I'll get my old thicker hair back.

I really love this shampoo. I wash my fine long curly hair 2-3 times a week and this in combination with the conditioner and scalp treatment make my curls more pronounced. Barely any scent. Not pregnancy safe for those in that boat, but great to help with thinning after baby and breastfeeding.

I’ve noticed a real difference in my hair since using this shampoo along with my biotin supplement. My stylist even commented that my hair looks healthier and is growing better. I have highlights, and I can now skip toner every other root touch-up, which has been a nice bonus. Overall, my hair feels stronger and looks better. I also found it at Costco for a better price, but I’m still happy with the product and results

I 100% tried this product not expecting any transformative results. Literally been struggling with my thin hair for decades! Absolutely NOTHING, not thickening shampoos, hair oils, not washing often/washing more often, washing just the roots, using no heat, taking biotin. Hair skin and nails vitamins, doing more inverted yoga to increase circulation, scalp massage and on and on, ever worked! This is CRAZY! 25 days on the entire kit in my pic attached. I can’t wait to see what 3-6 months looks like!! I’ll be updating!!! I currently use a wig because my thinning got so bad! I can’t believe I might finally be able to ditch the wigs and feel confident with my own hair within time!! Thank you guys for making such an effective product!!

Smells nice, lasts a long time (so good value) and leaves my hair feeling soft and smooth. In combination with the conditioner it enhances my naturally curly hair. I am never sure what people mean by "thick" hair. If this is meant as opposed to thinning hair, as in hair loss, it's hard to tell. I have seen comments like "I now see a lot of Baby-hairs" (here or in YouTube videos) I think that is just a bunch of internet babble. Korean products in general claim that they are focused on prevention as opposed to repair of already existing problems. With shampoo that means nourishing the scalp as opposed to trying to fix already damaged hair. I think about it this way: How much time, effort and products do most people put into their face skin? Your scalp is basically a continuation of the skin on your face. So why not try to take the same care of your scalp?

This product is excellent. Together with its conditioner, it has helped me a lot with hair loss. It leaves my hair clean, soft, and refreshed without drying it out. I also like that it gives my hair more volume and makes it look healthier. The shampoo has a nice texture, lathers well, and is easy to rinse out.

It seems to thicken hair- lathers and rinses well.

I bought the bundle one.i received the shampoo and conditioner 1st but i waited for the miracle in shower treatment and serum before using it. While using it a while ago,this is the 1st time that some of my hair was falling while I’m showering.usually after i blow dry my hair or while brushing.i’m not sure if i continue using this product 😅 my hair is soft though that’s why i gave 3 stars 😅

Après seulement deux utilisations, ce shampooing est incroyable : j’ai tout de suite remarqué la différence ! Mes cheveux sont plus épais, plus doux et paraissent vraiment plus sains. Le prix en vaut largement la peine.

Up to the standard

Expensive but effective. This product is very special. I have only used it one time since it's delivery and I can already see and feel differences in my hair and scalp. Can't wait to do further shampooing

Me gusta mucho pero la primera vez que lo compré, eran 2 frascos de 700 ml. Creo que lo compré en Costco , Y a un buen precio, el que me llegó es de 385ml. Y más costoso

Feels good on scalp. Using it for a few days so cannot say if makes my hair grew thicker but I feel refreshed after using it. Expensive but looks quality
