Women age faster.

The Yellow Emperor's Classic of Internal Medicine mentions that men and women have different growth cycles. For women, a cycle is 7 years, with bodily functions peaking at 28 years old, beginning to decline after 35, and menopause starting at 49. For men, a cycle is 8 years, with the body being most robust at 32 years old, and menopause beginning at 64. The Classic also states that for women, "at five sevens [35 years old], the Yangming meridians decline, the face begins to wrinkle, and hair begins to fall out." This means that after 35, the Yangming stomach meridian of the foot declines, leading to a yellowish complexion and brittle hair. Skin and hair growth and nourishment require nutrients; hair is a surplus of blood, and the spleen is the foundation of acquired essence, the source of qi and blood production. When the spleen and stomach are not functioning well, the body will prioritize abandoning less important parts to protect the health of other organs, and the skin and hair are usually the first to show these effects. To strengthen the spleen and nourish the stomach, you can drink the Sijunzi (Four Gentlemen) Tea. The ingredients are 5g Codonopsis pilosula, 5g Atractylodes macrocephala, 5g Poria cocos, and 2g Glycyrrhiza uralensis. Method: Wash the ingredients and place them in a thermos cup, then add hot water and steep for 15 minutes before drinking. This tea can replenish qi and strengthen the spleen. It can strengthen the spleen and enhance stomach qi for those with a weak spleen and stomach. Codonopsis pilosula tastes sweet, is neutral in nature, and enters the spleen and lung meridians.
