The author has been worried about the aging of his scalp and hair after he was 30 years old. At the hair dressing shop, I always get a "carbonated spring head spa", but I always thought that I could do it at home (I decided not to ask about the price of the dedicated device).
The other day, I found "Carbonated water massager for PET bottles" at the 100-yen shop "Ceria". It is an item that can be pre-washed and scalp massaged before shampoo using commercially available carbonated water in a PET bottle. According to the package, carbonic acid and massage can be expected to promote blood circulation in the scalp and make it easier to remove stains.
The tip of the massager is equipped with a protrusion and a stopper with a spring, and if you remove the cap of the PET bottle and replace it, you are ready to go. When the stopper is pushed in, the contents will come out, so use it by pressing it directly against the scalp.
When I pressed against gingerly, vigorously carbonated water is jetted Busha'! The stimulus from the fine bubbles and protrusions that popped was comfortable, and after shampooing as usual, I was refreshed more than I had imagined.
This time, I used carbonated water for about 40 yen per bottle, so the cost per bottle is very cheap. Even with carbonated water at room temperature, it is extremely cold in winter, so it is recommended that you wash it while facing down so that it does not hang on your body as much as possible.
You want to take good care of your scalp not only in the summer when it is sticky with sweat, but also in the winter when the blood circulation gets worse due to the cold. In other words, if you see a massager who is active all year round, please give it a try!
