In March, caring for hair post-winter requires attention due to lingering cold and vitamin deficiencies that cause dryness and brittleness. Experts recommend using nourishing masks and conditioners after washing hair to avoid split ends. Additionally, protective sprays can hydrate and shield hair. Choosing the right days for haircuts and treatments based on the lunar calendar can enhance hair health. Favorable days for cutting include March 4, 6, 10-13, while coloring is best on March 3, 5, 10, 11, 14, 22, 23, and 26. Unfavorable days are March 1, 2, 8, 27, and 29.
