Quick answer: Yes, you can shave above the knee. There is no medical reason not to. The old rule was about looks and upkeep: thigh hair is usually finer, and shaving leaves a blunt edge, so regrowth feels and looks more noticeable. The hair does not grow back thicker. The real issues with shaving your thighs are ingrown hairs, strawberry legs, and rough bumps, and all three come down to prep and exfoliation, not the razor.
If you grew up in the 90s or 2000s, you probably got The Talk. Not that talk. The shaving talk. Shave your calves, but whatever you do, do NOT shave above the knee. Your mom said it. Her mom said it. Nobody could explain why, but the rule was the rule.
I posted a TikTok with one line of on-screen text: "wondering why our mothers told us we shouldn't shave above the knee for our entire teenage life." It hit 4.6 million views, and the comments were full of women who avoided their own thigh hair well into their twenties. So let's settle it.
Where did the "don't shave above the knee" rule come from?
No dermatology textbook says thigh skin can't handle a razor. The rule was cultural, and it made a certain kind of sense:
- Thigh hair is often finer and lighter. Many women have softer, sparser hair above the knee than on their calves.
- Shaved regrowth feels different. Hair naturally tapers to a fine tip. Shaving cuts that tip off and leaves a blunt end, so regrowth feels stubbly and catches the light. It looks different. It does not grow back different.
- Nobody wanted the upkeep. Honestly, the rule was also about not signing up for a lifetime of full-leg shaving.
None of that means shaving above the knee is bad for your skin. It just means you should know what you're signing up for.
Does shaving make hair grow back thicker?
No. Shaving does not change the thickness, color, or growth rate of hair. The blunt end is what makes regrowth feel coarser. This has been tested and debunked many times.
What actually goes wrong when you shave your thighs?
Ingrown hairs. Thighs are a prime spot for ingrowns, especially the inner thighs and where the leg meets the bikini line, because skin rubs there. Dead skin can trap regrowing hair under the surface.
Strawberry legs. Those dark dots after shaving are usually open follicles where oil and dead skin have built up and darkened on contact with air. Sometimes it is just stubble showing through the skin. Regular exfoliation and a clean shave help them look less noticeable.
Keratosis pilaris (KP). The small, rough bumps on the backs of thighs, upper arms, and bum are KP, often called "chicken skin." It is one of the most common skin textures there is, and it is harmless. Dragging a razor over rough, bumpy skin tends to leave it looking redder. We have a full guide to exfoliating gloves for keratosis pilaris.
The fix for all three is the same: exfoliate the day before you shave and moisturize after.
How to shave above the knee without ingrown hairs
1. Exfoliate the day before you shave, 1 to 2 times a week. In a warm shower, use an exfoliating glove on bare, wet skin with no soap. Work in light circles for 30 to 60 seconds, then rinse. This lifts the dead skin that traps hairs, and giving your skin a day to settle means the razor meets smooth, calm skin instead of freshly exfoliated, sensitized skin. Gloves are not for daily use.

2. Never dry shave. Warm water plus a slick shave cream, gel, or oil.
3. Shave with the grain. Going against the grain gets closer, but it is also more likely to cause ingrowns on thighs. One pass with the grain is enough for most people.
4. Moisturize within a few minutes. Pat dry and apply lotion or a few drops of body oil while skin is still slightly damp.
5. Swap your blade. A dull blade drags, and dragging causes bumps. If it's pulling, it's done. Our Safety Razor takes standard double edge blades, so swapping in a fresh one is quick and easy.
Which exfoliating glove should you use before shaving?
- Most skin: the Original Deep Exfoliating Glove, our bestseller.
- Sensitive skin, KP, or freshly shaved inner thighs: start with the Luxe glove. It is our gentler option. More on that in the best exfoliating gloves for sensitive skin.
Both are made from a plant-based fabric spun from reed plant fibre, hand-cut and hand-sewn, and no soap is needed.
FAQ
Is it okay to shave above the knee?
Yes. There is no medical reason to avoid shaving your thighs. The old rule was about how regrowth looks and how much upkeep it takes.
Does shaving above the knee make hair grow back thicker?
No. Shaving leaves a blunt tip, so regrowth feels coarser, but the hair's thickness, color, and growth rate stay the same.
Why did our moms say not to shave above the knee?
Mostly looks and maintenance. Thigh hair is often fine and light, shaved regrowth is more noticeable, and nobody wanted to start full-leg shaving forever.
How do I prevent ingrown hairs on my thighs?
Exfoliate 1 to 2 times a week with an exfoliating glove, ideally the day before you shave. Shave with the grain on wet skin with plenty of slip, and moisturize right after.
How do I get rid of strawberry legs?
Exfoliate regularly, ideally the day before you shave, use a sharp blade with shave cream, and moisturize after. That helps the dark dots look less noticeable over time.
Is KP on the thighs normal?
Very. Keratosis pilaris is one of the most common skin textures and is harmless. Gentle exfoliation plus daily moisturizer helps skin feel smoother.
The bottom line
Shave above the knee if you want to. Skip it if you don't. Either way, it's your call, not a rule. If you do, exfoliate the day before, shave with the grain, and moisturize after. With 500,000+ gloves sold and 4.5 stars across 4,600+ reviews, find your Wildpier glove here.
