Does vaping cause hair loss?

The honest state of the research

There are no large studies that directly prove vaping causes hair loss in humans. What does exist: plenty of research on how nicotine affects blood flow, hormones and oxidative stress, and growing evidence that vaping affects all three in similar ways to smoking.

Most of the research linking nicotine to hair loss comes from studies on smokers. Because vaping shares nicotine and many of the same mechanisms, hair specialists generally treat the two as similar risks. The 2022 Kavdaya study examined how nicotine constricts blood vessels and limits blood flow to hair follicles, finding that nutrient-deprived follicles can thin and shed.

The honest summary: vaping has plausible mechanisms for contributing to hair loss, and many vapers report noticing more shedding. The evidence is not yet strong enough to call it a definite cause.

How vaping may affect hair

Who is most likely to notice

Vape-related hair loss is most likely to be noticeable in certain groups.

• People genetically prone to pattern baldness. Vaping accelerates what would happen anyway.
• Heavy daily vapers, especially those on 20mg nic salts or higher.
• People under stress or with nutritional deficiencies. Vaping adds to an already-loaded system.
• People with thyroid or hormonal conditions already affecting their hair.
• Post-pregnancy women in the postpartum shedding phase. Vaping can extend it.

What vape-related hair changes look like

If vaping is contributing to your hair loss, it usually shows up in specific ways.

What you can do

If you have noticed thinning since you started vaping, a few steps make a real difference.

1. Reduce your nicotine strength

   The biggest single change. Going from 20mg to 10mg or 6mg reduces vasoconstriction and lets more blood reach your scalp. Often the only change needed for noticeable improvement.

2. Drink more water

   Vaping is mildly dehydrating. Proper hydration helps your scalp stay healthy and supports the rest of your body in dealing with oxidative stress.

3. Eat for hair health

   Iron, biotin, vitamin D and protein all matter. Leafy greens, eggs, nuts, fish and lean meat support healthy hair growth. Particularly important if vaping is using up some of your antioxidant capacity.

4. Scalp massage

   A daily 5-minute massage stimulates blood flow to the follicles. Counteracts some of the vasoconstriction effect from nicotine. Costs nothing.

5. Consider minoxidil if loss is significant

   Sold as Regaine in the UK. Available over the counter without prescription. Backed by strong evidence for pattern hair loss in both men and women.

6. See a GP for a blood test

   Hair loss can be linked to iron deficiency, thyroid issues, vitamin D deficiency and other conditions that have nothing to do with vaping. Worth ruling out the easily-fixed causes first.

7. Consider stopping nicotine entirely if loss continues

   If your hair is important to you and you have tried the above without improvement, a few months without nicotine often shows whether it was a contributing factor.
