Ingredients
How to use
Use twice a day, such as in the morning and evening. Use after thoroughly wiping off excess water after washing your hair, or on a dry scalp. Toss your hair up, spray close to your scalp, and work in with the pads of your fingers. (Spray approximately 10 times over the entire scalp) < effectively>. After application, use the pads of your fingers to massage the entire scalp in a moving motion to promote blood circulation and make it more effective. For a fluffier finish, use a hair dryer to ensure that air reaches the roots of your hair.

I use it to massage my scalp after bathing. It feels great as a suit.
It leaves your scalp feeling refreshed, so I recommend it especially in the summer. It leaves your hair soft and fluffy, and gives it volume. However, if you pump too much at once, it can cause sagging, so I use two or three pumps at a time, massaging my scalp as I go.
It has a refreshing, clean scent. I tried it for scalp care because I was concerned about frizzy hair after giving birth, but after using it for about three weeks, it didn't have much effect on the frizz. It did give my hair a little volume after drying, which was nice. I spray it mainly on the scalp around my bangs, but if I'm not careful, it can run down onto my face and make my eyes feel cool, so I recommend spraying it while looking up and massaging it in quickly.
I'm glad I bought this. My scalp no longer itch. I used to use the organic Kamitsukoi scalp lotion, which was great because it didn't make my hair turn gray, but it wasn't moisturizing... which was disappointing. Since I ran out of Kamitsukoi, I tried Prior, which is easy to buy, and when I rub it in after a bath, it feels so cool and comfortable. It's a spray type, so it's easy to use. My scalp has also become softer, so I'm very satisfied with this product. I recommend it.
I was hesitant to buy it at DS, but I had high hopes for it, considering the price. The packaging is cool, and you can see how much is left. It dispenses a lot at once, so be careful as it can drip. Also, if you put too much on, it can harden and make your hair look like you've applied hair styling product to a specific area, which can look uncool if you're seen up close. The scent is similar to the Tsumura product I used before. It seems to be effective not only for the scalp but also for the hair, and since this is my first time using it, I was hoping for good results, but when I looked at the ingredients, it didn't seem to contain much. I should have read the ingredients more carefully before purchasing. Oh, and it's a shame I had to bring my reading glasses with me when I went shopping.
