During menopause, the ovaries gradually stop producing oestrogen and progesterone. The decline in oestrogen levels, in particular, affects the skin and nails because oestrogen helps retain moisture in these areas. When oestrogen levels drop, nails can become drier, weaker, and more brittle.
As you age, collagen production also decreases. Collagen is an important protein that supports the skin and nails. During menopause, the reduction in oestrogen levels further decreases collagen production. This results in reduced strength and elasticity in the nails, increasing the likelihood of breakage or splitting.
In general, nails become more brittle as you get older. Brittle nails not only break more easily but can also split, dry out, and discolour. They grow back more slowly and may develop ridges. Many people with weak nails also experience dry and cracked cuticles, dry hands, or dry skin in general.
Although weak nails are not immediately associated with menopause, it is a complaint that becomes more common during this phase. In particular, the risk of brittle nails increases during postmenopause. A possible explanation is the consistently low oestrogen levels, which further reduce collagen production. This affects the skin, hair, and nails.
