Yes, pubic hair turns gray as you get older, just like the hair on your head. It typically starts later than scalp hair, with the earliest signs appearing around age 30 in men and 36 in women, though many people won’t notice it until well into their 40s or 50s.
Why Hair Turns Gray Anywhere on Your Body
Hair gets its color from a pigment called melanin, which is produced by specialized cells (melanocytes) inside each hair follicle. As you age, the stem cells that replenish those pigment-producing cells gradually decline in number and function. With fewer of them doing the work, each new hair that grows contains less pigment. The result is hair that looks gray, then eventually white when pigment production stops entirely.
This process is driven by several overlapping factors: accumulated damage from free radicals, DNA damage within the follicle, and reduced activity of the key enzyme responsible for making melanin. Stress can accelerate the process too. Adrenaline-related signaling from the nervous system can deplete pigment stem cells in the follicle, causing irreversible pigment loss. That mechanism applies to hair follicles everywhere on your body, including the pubic region.
When Pubic Hair Starts to Gray
Graying generally follows a predictable sequence across the body. Scalp hair usually goes first, often starting at the temples in your 30s. Pubic hair tends to follow later because the follicles in that area operate on a different growth cycle and are influenced by sex hormones that can delay the process somewhat.
A forensic study on the timing of pubic hair graying found that the earliest possible onset was around age 30 in men and 36 in women. By the mid-40s to early 50s, most people have at least a few gray pubic hairs. More advanced graying, where gray hairs clearly outnumber pigmented ones, was consistently seen starting in the late 40s to 50s, with significant individual variation. Some people in their early 60s still had minimal graying, while others were nearly fully gray by their late 40s.
Genetics Play the Biggest Role in Timing
The single strongest predictor of when your pubic hair will gray is your family history. If your parents went gray early on their head, you’re likely to see earlier graying everywhere else too. The same genetic factors that control melanin production in scalp follicles govern pubic follicles.
Beyond genetics, certain nutritional deficiencies and health conditions can push the timeline earlier. Low levels of trace minerals like iron, zinc, and copper have been linked to premature graying across the body. Thyroid disorders and some autoimmune conditions can also play a role. Smoking is another well-documented risk factor for earlier graying.
Graying Isn’t the Only Change
Color is just one part of how pubic hair changes with age. The hair also becomes thinner, finer, and less dense over time. Individual strands shrink in diameter, so what was once thick and coarse gradually becomes softer and lighter. Many people also notice that the overall coverage area decreases, with hair becoming sparser, particularly after age 50 or 60.
Hormonal shifts drive much of this thinning. Testosterone plays a key role in maintaining pubic hair growth for both men and women. As testosterone levels naturally decline with age, pubic hair can thin noticeably. For women going through menopause, this decline is often more pronounced. Low thyroid function can compound the effect. So while graying is the most visible change, it’s usually accompanied by a gradual shift toward thinner, fewer hairs in the pubic area.
Can You Prevent or Reverse It?
There’s no reliable way to prevent pubic hair from graying. The underlying process, the depletion of pigment stem cells, is currently considered irreversible once it happens. Maintaining adequate nutrition, particularly enough B vitamins, iron, and zinc, may help avoid premature graying, but it won’t stop the natural age-related process.
Some people choose to dye pubic hair, though the skin in that area is more sensitive than the scalp, and standard hair dyes can cause irritation or allergic reactions. Products specifically formulated for sensitive skin are a safer option if you go that route. Most people, though, simply find that pubic graying is one of those quiet signs of aging that arrives without much fanfare and doesn’t require any action at all.
