Short answer: no. Shaving doesn’t change how fast or thick your hair grows.
Hair growth is controlled by your hair follicles, which live beneath the skin’s surface. Shaving only cuts the hair at the surface—it doesn’t touch the follicles. This means shaving has zero impact on the speed or thickness of regrowth.
So why does it seem like hair grows back thicker after shaving? It’s all about the blunt ends.
Why Hair Looks Thicker After Shaving
When you shave, you’re cutting hair straight across, leaving a blunt edge. This blunt end feels coarser to the touch and looks thicker because it’s not tapered like natural hair growth.
Here’s the kicker: the actual texture, color, and growth rate of your hair remain the same. Once your hair grows out past the blunt edge, it’ll look and feel just like it did before.
What Really Affects Hair Growth?
If shaving doesn’t make hair grow faster or thicker, what does? Hair growth is influenced by:
Hormones & Hair Growth
Hormones play a starring role in how our hair grows, and androgens are the main characters in this drama. Higher levels of androgens—like testosterone—can cause hair to grow thicker and faster. This is why many people see changes in body hair during puberty, pregnancy, or menopause. These changes happen when hormone levels fluctuate a lot.
Hormonal imbalances, like those from polycystic ovary syndrome (PCOS), can cause hair to grow in unexpected areas. You might notice thicker hair in places you don’t want it. Keeping your hormones in check can make a noticeable difference in your hair growth journey.
Hair Growth & Genetics
Ever wonder why you have your dad’s thick, wavy hair or your mom’s fine, straight strands? Blame (or thank) your genes. Genetics determine everything from the color and texture of your hair to how quickly it grows. If your family tree is full of lush locks, you’re more likely to have a healthy head of hair too.
On the flip side, if thin or slow-growing hair runs in your family, you might face the same challenges. You can’t change your DNA, but knowing your genetic traits can help you set realistic goals.
How Age Affects Hair Growth
As we age, our hair often decides it needs a break from the hustle and bustle of rapid growth.
Hair tends to grow slower and finer with each passing decade, which is why many older adults notice thinning hair or less body hair. This slowdown is due to a decrease in hormone production and changes in the hair growth cycle itself. The follicles get a little lazier, spending more time in the resting phase and less in the growth phase.
You can’t turn back time, but taking care of your scalp and using gentle hair products can keep your hair looking great at any age.
The Role of Health and Diet in Hair Growth
You are what you eat—and so is your hair! Nutritional deficiencies can lead to weaker, slower-growing hair.
Lack of essential nutrients like iron, biotin, and vitamins A, C, and E can impact hair health. Hormonal imbalances from issues like thyroid disorders or high stress can slow hair growth or cause thinning. Eating a balanced diet rich in lean proteins, leafy greens, and healthy fats can support stronger, healthier hair. And don’t forget to stay hydrated—your hair needs moisture from the inside out.
Talk to your doctor if you notice sudden changes in your hair. A quick blood test might show if you have nutritional gaps or hormonal issues.
Shaving, plucking, or waxing won’t change any of these factors.

FAQs
Does shaving make hair grow back thicker or faster?
No, shaving doesn’t change how your hair grows. It only cuts hair at the surface, leaving a blunt tip that can feel coarser. Your hair’s growth rate and texture are determined by genetics and hormones.
Why does shaved hair feel thicker?
Shaving leaves a blunt edge, which feels rougher than the naturally tapered tips of unshaven hair. This bluntness makes hair seem thicker or darker, but it’s not actually growing back differently. Once the hair grows out a bit, it softens again.
How can I slow down hair regrowth?
You can try:
- Waxing to weaken hair follicles
- Sugaring for gentle hair removal
- IPL devices like RoseSkinCo’s Lumi
- Tweezing for small areas
- A healthy diet to support normal hair cycles
Why doesn’t shaving affect hair thickness or growth speed?
Hair growth happens at the follicle level, beneath the skin. Shaving only cuts hair at the surface, so it doesn’t affect the follicle or its growth cycle. Hormones and genetics control hair thickness, texture, and growth rate. This is why shaving has no impact on how your hair grows back.
What role do hormones play in hair regrowth?
Hormones, particularly androgens, influence hair thickness and growth speed. Higher androgen levels can lead to coarser or faster-growing body hair. Hormonal changes during puberty, pregnancy, or menopause can also temporarily alter hair growth patterns.
How does IPL reduce hair regrowth?
IPL (Intense Pulsed Light) targets hair follicles with light pulses, disrupting the growth cycle. Over time, the follicles produce finer, sparser hair or stop producing hair altogether. With regular use, IPL significantly slows down regrowth, making it a great alternative to shaving or waxing.
