Softening hair: Generally speaking, adding a little vinegar or tea when shampooing can effectively soften hair and soften hair that is too hard. The principle of this softening is that a weakly acidic or weakly alkaline environment softens the structure of the hair to a certain extent, but you should not add too much vinegar, otherwise it will damage the hair. In addition, it is also important to wash the scalp frequently. Some people's hair may be too hard because of the accumulation of scalp garbage, causing moisture to be unable to be injected into the hair follicles. 2. Replenish moisture: Boys with too hard hair may lack moisture, or their hair follicles may have a naturally greater demand for moisture. In this case, we can wash our hair frequently and use some shampoo that replenishes moisture, or we can use some conditioner that moisturizes the hair roots. As the name suggests, "hair care" is to replenish the lost nutrients of the hair and repair and rebuild the hair. Generally speaking, you should not use too much conditioner. Conditioning your hair immediately after washing can achieve the best effect. In addition to making your hair soft, it can also remove static electricity problems.
