Yellow dry hair and gray hair is caused by deficiency of kidney energy and insufficient qi and blood.
In Chinese medicine theory, the kidney’s splendor is in the hair. Kidney energy is manifested in the hair, and if kidney energy and essence are sufficient, the hair will be dark and shiny. If there is insufficient kidney qi and essence, the hair will be yellow and dry and turn white.
Another reason is insufficient qi and blood. Chinese medicine says that hair is the rest of blood. If there is enough qi and blood, the hair is nourished by qi and blood, and if there is enough nutrition, the hair will be black and shiny. If there is insufficient qi and blood, the hair is undernourished and will become yellow and dry, or even turn white.
Those with insufficient kidney energy can take Seven Treasures Beauty Beard Dan, and those with insufficient qi and blood can take Nourishing Blood Hair Capsule.
Taking proprietary Chinese medicines needs to be guided by a Chinese medicine practitioner under the guidance of evidence, do not use medicines blindly, so as not to cause uncomfortable reactions.
