I've been using this for three days after getting a digital perm. When I rinse it out, my hair feels smooth and comfortable, but when I dry it, it swells up... The next day, my hair is set, but it's still hard to run my fingers through... It's still as damaged as before, and my hairdresser keeps telling me it's damaged (lol). Considering this alone, it seems pointless to use it, but since I started using it, my perm seems to be lasting better. Maybe my regular care is better, though. Considering how it affects my hair, I think it would be fine to just use this series of shampoo... I'm not sure if I'll buy it again.
I've just finished using up the 50g size of this treatment, so I'm posting about it. I used it together with the shampoo from the same series. I used it for a few days after getting a perm at the salon. Since I don't go to the salon that often, it lasted quite a while. I didn't like the shampoo because it had a strange, pungent smell, but this treatment smells nice. I also found it to be highly moisturizing. I used to use Of Cosmetics' high-moisturizing treatment (rose scent) and found it to be even more moisturizing. I have a good impression of it, but would I use it on its own? Well... I think this product is probably only effective when used in combination with shampoo, so as long as I don't like shampoo, it will be difficult for me to continue using it.
I used it together with the 1-ER shampoo from the same line. I think I used it for about four days after getting my hair colored at the salon. To sum up, if this helps my color last longer, I'm willing to put up with it for a few days. I'm not sure if it was the shampoo's fault or my own, but after drying my hair, I noticed more frizz and flyaways than ever before. To best describe it, it felt fluffy. I think it would be perfect for those with less volume or who don't like their hair to be flat. However, since I have hair that's prone to frizz and flyaways, and I usually use shampoos that tame them, I think it just didn't suit my hair type. My hair felt unsettled when I woke up in the morning, and it was difficult to style. (I had a short haircut at the salon, so maybe it's because I'm not used to the length yet.) The scent is very nice. The natural scent, reminiscent of burning aroma oils, is soothing. I don't think it lingers after drying. I like the scent, so it's a bit disappointing. As for how long the color has lasted, it's been a week since I went to the salon, and I've now gone back to using regular shampoo and conditioner, but I'm happy with it so far. I've heard that how well the alkalinity is removed by washing your hair in the days after coloring can affect how long the color lasts, so if the color lasts after just a few days of use, I think it's good value for money, considering the frequency of visits to the salon.
I use this in combination with 1-er. I use this for the first 5 days after coloring and when I wash my hair for the first time. It's a must-have for making the color last longer.
I used it with 1-ER shampoo. My hair was pretty damaged from the digital perm and color, but this made it moist and manageable! However, it's a little pricey, so I probably won't buy it again.
