Perhaps on every second jar that contains a hair mask, you can see the inscription “Apply to the ends of the hair.”
However, if you obediently apply only a couple of centimeters of hair, you shouldn’t count on luxurious curls.
By the generic term "hair ends" cosmetic manufacturers mean the hair that is below the ponytail.
So, to understand which part of your curls needs to be moisturized, nourished and saved from breakage, all you need to do is tie a ponytail.
After this, you can safely apply the mask to the hair that is below the elastic band.
By the way, about split ends - according to professionals, if your hair is split, only scissors will help - there is no point in restoring the strands.
Another important point: you should choose a mask based on your hair type. You will only see the result with regular use.
Finally, an interesting fact: modern hair masks can be used as conditioners, although in this case they should only be kept on for 2-3 minutes, not the recommended 10.
