Hair treatment I bought with my own money

This is an elastin treatment for damaged hair that I recently purchased.

After shampooing, take an appropriate amount, apply it evenly to your hair, and rinse it off after about 2 to 3 minutes; you will feel that your hair has become much softer.

Since it contains argan oil and amino acids, I also feel like it might be better for some reason.

It would be best for your hair not to get perms or dye it, but,

Since that is difficult, I should at least do treatments consistently.
