Hair and nail changes in pregnancy: thicker hair, brittle nails, shedding

You may look in the mirror and notice that your hair suddenly seems fuller, or that your nails are behaving differently. In pregnancy, hormones influence the hair and nail cycle; most of these changes are harmless and settle on their own.

What can happen to your hair?

Every strand goes through growth, resting and shedding phases. When oestrogen rises in pregnancy, strands in the resting phase tend to stay in place longer, so many people see thicker, livelier hair. Some people notice a change in texture: straight hair may wave, and oily hair may turn dry, or the other way round.

The same hormones can make fine hair on the face, arms or belly a little more visible. This usually fades in the months after birth.

Why do nails change?

Some people find their nails grow quickly and feel stronger; others find them softer, peeling or easily broken. Mild ridges or colour differences can appear too. If your hands are washed often and stay wet, dryness adds to the picture.

Shedding after birth

About 2–4 months after birth, you may see an unusual amount of hair in your brush or the shower. This happens when the strands that were held in place during pregnancy leave the resting phase together. It is very common and usually slows within a few months. Breastfeeding or not does not clearly change this; every feeding path is respected.

8 tips that help right away

1. Brush gently with a wide-toothed comb, starting from the ends.
2. Squeeze wet hair with a towel instead of rubbing hard.
3. Avoid very tight buns, ponytails and elastics.
4. Use hot dryers, straighteners and curling tongs sparingly.
5. Ask your doctor or midwife before dyeing, perming or chemically straightening.
6. Keep nails short and apply moisturiser.
7. Wear gloves for washing up and cleaning.
8. Eat a balanced diet: enough protein, iron, vegetables and fruit support hair and nails.

Before taking supplements

Some vitamins or supplements marketed for hair and nails may not be suitable in pregnancy. Apart from the prenatal vitamin your doctor recommends, always ask before adding anything. For skin changes, you may also like the Guide article “Skin changes and stretch marks in pregnancy”.

How you feel matters too

The look of your hair or nails can affect mood for some people. You may feel uneasy about what you see in the mirror, and that is very understandable. A fresh haircut or keeping your nails short and tidy can help you feel good during this temporary phase. Most changes settle gradually after pregnancy.

When to contact your doctor

• Your hair is falling out noticeably, in patches or in clumps during pregnancy
• Hair loss comes with extreme tiredness, paleness, palpitations, feeling cold or weight changes
• Nails show a lasting dark streak, severe pain, swelling, pus or a bad smell
• Shedding continues, or thinning does not recover, even 6–12 months after birth
• Your scalp is red, widely itchy or sore

Frequently asked questions

My hair got thicker. Will it go back after birth? For most people, yes. Shedding after birth is the release of the extra strands held during pregnancy, and it usually balances out by itself.

Can I use nail polish or gel on my nails? Occasional use in a well-ventilated room is fine for most people; tell the nail technician you are pregnant and ask your doctor if you are unsure.

Can I do anything to stop shedding? Gentle care and a balanced diet help, but shedding after birth usually ends by itself over time.
