Why are shampoo sandwiches so good?
The biggest reason is the new concept of "protecting before washing."
Hair fibers tend to open up when wet, and shampooing in that state makes them susceptible to friction damage.
Therefore, by applying a treatment before shampooing, you can protect the surface of your hair and prevent it from becoming dry and brittle.
the result:
- Easy to get glossy finish
- Becomes soft to the touch
- Prevents color fading
- The ends of the hair are less likely to spread
It becomes easier to feel the benefits.
What hair type is it suitable for?
✔ Your scalp feels oily, but your hair ends are dry ✔ You repeatedly color your hair ✔ Your hair tends to get frizzy in the winter ✔ Your hair is wavy or curly and prone to dryness ✔ You're concerned about damage, but you don't have time
It is especially suitable for those with these problems.
Caution: There are cases where it is not suitable.
Shampoo sandwiches use a larger amount of treatment than usual, so if you have thin hair that is difficult to add volume to, it is recommended that you adjust the amount.
The ONSENSOU Repair Mask has a lightweight, silicone-free finish, but it's a good idea to try a small amount first.
