One of the most common grooming myths is that shaving makes your hair grow back thicker and faster. Whether it’s your face, legs, or anywhere else, many people believe the simple act of shaving somehow changes how the hair grows. But is there any truth to this? Let’s break it down.
Does Shaving Affect Hair Thickness or Speed of Growth?
The short answer: no, shaving does not make hair grow back thicker, darker, or faster.
Here’s why:
- Hair growth happens beneath the skin in the follicle. Shaving only cuts the hair at the surface, not at the root where growth is controlled.
- When shaved hair grows back, the blunt edge from the razor can make it feel coarser or look darker. But the hair’s structure, density, and colour remain unchanged.
- Multiple studies, including those reviewed by the National Library of Medicine, confirm that shaving has no impact on hair growth rate or thickness.
Why Does It Seem Like Hair Grows Back Thicker?
- Blunt Tips: A razor leaves each hair with a flat, blunt end. This feels rougher than the naturally tapered tip of uncut hair.
- Contrast Against Skin: Fresh stubble can look darker because the hair hasn’t been lightened by sun exposure or natural wear.
- Growth Cycles: Hair grows in phases. If you shave during a growth spurt, it may appear as though shaving “caused” the faster regrowth.
How to Get a Smoother, More Comfortable Shave
If shaving doesn’t affect growth, what does matter is how you shave. Using the right tools and products makes all the difference:
- Choose eco-friendly razors: At Smart Shave, our reusable razors are designed for a close, smooth shave without irritation.
- Use shaving products with skin benefits: Our gels and foams include vitamin E & aloe vera, which soothe and protect your skin.
- Shave in the right direction: Always shave with the grain to reduce irritation and ingrown hairs.
- Moisturise afterwards: A hydrating post-shave routine keeps your skin healthy and reduces dryness.
The Bottom Line
Shaving doesn’t influence how quickly or thickly your hair grows back—it’s simply a persistent grooming myth. What really matters is your technique, your skincare routine, and the quality of the products you use.
