If your hair looks good, but when you touch it you find it dry and stiff, you probably wonder if you need a haircut. Well, do not run into conclusions and use this old trick which requires only a glass of water to find your answer.
Put aside a lock of hair and soak it into a cup of water. If the hairs float on the surface, it means that you do not have to worry and you do not need to schedule a haircut, as your hair is in an excellent condition.
But, if your hair sinks, it means that it is fragile and weak and the only solution to this problem is the scissors.
This trick is efficient and beneficial due to the fact that water is able to penetrate the thin and weak hair much more easily, meaning that this type of hair is much more susceptible to losing its shape and color under the influence of moisture. On the other hand, healthy hair floats on the surface of the water and maintains its previous shape, more or less, even after exposure to moisture.
