Of course, it can also be used during the day. It protects against heat from hair dryers and hair irons, as well as UV damage during the day, so it's also recommended to use it before going out. *1 Centella asiatica extract (moisturizing) *2 Centella asiatica extract (moisturizing), hydrolyzed hyaluronic acid (moisturizing), hydrolyzed keratin (repairing) *3 External repair helps the ingredients that penetrate into the hair to stay in place longer.

I happened to come across this product in a shop just when I was thinking that my usual hair oil was about to run out. I usually choose thick, rich oils, but the cute packaging attracted me and I bought it. Personally, it was a hit! I have very long hair that reaches my waist and buttocks, and it's prone to damage, whether it's because the ends have tapered, or because of age, or because the dryness is so severe that it triggers a dryness warning. Lately, even with the same care as usual, I've been noticing that the ends of my hair are frizzy and feel brittle when I comb them with my hands. I use it on dry hair after blow-drying, and the smooth oil penetrates quickly, leaving my hair feeling calm and silky to the touch. The effects seem to last the next day, and I'm enjoying smooth, moisturized hair. I'll definitely be buying it again!
The cute purple packaging is adorable! This oil has a smooth texture. It's not sticky and blends in easily! My hair, which had become dry due to UV rays and the damage caused by coloring, was left moisturized and lasted until the next morning, which I was very satisfied with. It's also great for everyday morning hairstyles! #riasu #Riasu #NightVeilCICAHairOil #RiasuItem
One pump was just right for my semi-long hair. It's a light oil that leaves hair smooth and shiny when massaged in! The citrus scent is refreshing and not too strong, so it's easy to use.
#riasuriasu provided this deep moisture CICA shampoo/treatment/hair oil. Formulated with CICA's unique formula*1, this product provides dual care for your hair and scalp! *1 It contains over 94% Centella asiatica extract (moisturizing)*2 and a generous blend of serum ingredients for salon-quality results. *2 This cute, pale purple shampoo contains water (excluding cleanser), lathers well, and cleanses thoroughly, even to the scalp. The moon citrus scent is relaxing. Massage the treatment into your hair, focusing on the ends. If you're concerned about damage to your ends, we recommend massaging it in and wrapping a warm towel around it for 5-10 minutes as a warm towel pack. ◎ Apply the oil before using a hair dryer. It's non-greasy, so it's recommended. Great for morning styling too! ◎ #Riasu #NightVeilCICAShampoo #RiasuShampoo
\Review/After towel drying, I applied one pump of hair oil to my long hair and then dried it! One pump dispenses a lot, so even on long hair, one pump was enough for a perfect finish without feeling sticky. This also has a refreshing scent, reminiscent of nature and forests. It's my favorite scent. I tried using it in the morning after styling my hair for UV protection, but it left a slightly sticky feeling. I thought using half a pump might eliminate the sticky feeling! Be careful not to apply too much. I also used the shampoo, and it's very good. It left my hair moisturized and smooth, and it felt soft! It also has just the right amount of smoothness, so it's great for people who like smooth hair. It leaves my hair smooth, so I'd like to use it the day before I plan to down my hair the next day, or when I want to unwind from the day's fatigue, as the scent was very relaxing. I hope this review is helpful. #riasu #Riasu #NightVeilCICAShampoo #RiasuShampoo #CICASerum #Shampoo #Moisturizing #RecommendedShampoo
