Can Houttuynia cordata treat white hair?

Generally, Houttuynia cordata may have an auxiliary regulatory effect in cases of premature graying caused by specific conditions such as excessive internal damp-heat, but it has no significant effect on gray hair resulting from other causes. If abnormalities occur, it is recommended to seek timely medical advice. Detailed explanation is as follows:

When gray hair results from excessive internal damp-heat affecting follicle nutrient absorption and melanin production, Houttuynia cordata, with its properties of clearing heat, detoxifying, and promoting diuresis, can be helpful. Consuming Houttuynia cordata or applying it externally to the scalp can aid in eliminating internal damp-heat, improving the scalp environment, and thereby providing better growth conditions for hair follicles to some extent, slowing the development of gray hair, although it is difficult to completely reverse the graying process.

However, for gray hair caused by genetic factors, aging, excessive mental stress, nutritional deficiencies, or other reasons, Houttuynia cordata cannot directly affect melanocyte function, alter genetic factors, or supply key nutrients lacking in the body. Therefore, it cannot fundamentally resolve the issue of gray hair, and simply using Houttuynia cordata is unlikely to result in any noticeable return to natural hair color.

Houttuynia cordata should not be blindly regarded as a treatment for gray hair. If premature graying occurs, the underlying cause should first be identified, and improvements should be made under the guidance of a physician using scientifically appropriate methods, to avoid delaying proper intervention due to overreliance on Houttuynia cordata.
