What it is
You want to grow your hair out, but you end up cutting it because you're worried about damaged ends. Covering up your wavy hair with a perm only makes it even more damaged... Don't feel sad and think, "I can't take the time to care for my hair." Don't give up on your current hair, and enjoy it freely. This intensive hair serum goes one step beyond conditioning your scalp and hair with shampoo. 1. Deep ocean water*1 delivers beauty ingredients deep into the hair. No matter how good beauty ingredients are, they're useless if they don't penetrate deep into the hair. That's why we've generously formulated it with deep ocean water*1 from Cape Muroto, making up 40% of the total formula. With a higher penetration power than purified water, 50 types*2 of beauty ingredients penetrate deep into the hair. This serum leaves hair moisturized and healthy, leaving it smooth and shiny all the way to the ends. *1: Seawater *2: Contains fragrance ingredients 2. Repairs cuticles and protects moisture. When hair cuticles peel due to damage from hair coloring, heat from hair dryers, and UV rays, they can become dry and brittle. To restore damaged hair to its original condition, this formula contains ingredients derived from edelweiss*1 and cumin extract. Additionally, nine amino acids*2 repair cuticles, leading to stronger, more resistant hair. *1: Edelweiss flower/leaf extract *2: Sodium dilauramidoglutamide lysine, serine, glycine, glutamic acid, alanine, lysine, arginine, threonine, proline 3. A luxurious blend of 50*1 beauty ingredients. A blend of 50*1 naturally derived beauty ingredients is included to enhance your current hair beauty. Moisturizing ingredients such as squalane hydrate the hair and scalp, while beauty ingredients such as pea-derived ingredients*2 promote firm, resilient, and durable hair, while argan oil*3 protects the hair. You will be amazed at how smooth and smooth your hair will become the more you use it. *1: Contains fragrance ingredients *2: Hydrolyzed pea protein *3: Argania spinosa kernel oil

I wanted to compare this mineral hair essence with the Repair Serum, which has received many harsh reviews, so I tried it. It wasn't bad, and somehow it was good. I sprayed it on after towel drying. It takes a little time for it to penetrate, so if you wait a little while after applying skincare products and then blow-dry, your hair will noticeably become softer and fluffier! This lasts until the next morning. I suspect the common complaints about hair becoming difficult to run your fingers through are due to people spraying it on and then blow-drying it immediately. You'll feel the full effect if you use a generous amount. It's also good for the scalp, which is another plus. However, the cost-effectiveness isn't great. It claims to be good for fixing bedhead in the morning, but I thought it would be a waste and not quite the right fit. It's a good product, but I've decided to stick with the Repair Serum.
At first, I used it after shampooing and before drying my hair, but I didn't feel much effect. However, when I used it in the morning like a hair straightening water, it was very moisturizing and made my hair manageable without the need for hair oil or wax! It also has a citrus scent that seems to be soothing in the morning. However, unlike hair straightening water, it takes a little longer to dry. Also, the cost performance is not good, so I'm not sure whether to buy it again. I might buy it again if it's cheaper as a set.
I bought this as a set with shampoo. The reviews were low, so I used it without any expectations, but it's absolutely great! It moisturizes and manages my hair perfectly, without any sticky, dry, or tangled mess. I have long, colored hair that breaks and gets damaged, but it was absolutely great to use. The reviews were so low I felt bad for my hair, so I ended up writing a review. It's not perfect because it doesn't mean it has to be this way.
