No, cutting your hair does not actually make it grow thicker.
Understanding Hair Thickness
The actual thickness of your hair strands, also known as hair density, is primarily determined by factors that are internal and largely unchangeable through cutting.
According to the reference, the thickness of your hair strands is determined by factors like your genetics, environment, age, and health. Cutting the ends of your hair will not alter your hair density.
Why Hair Might Appear Thicker After a Cut
While cutting doesn't change the biological thickness of your hair, it can certainly make it appear thicker.
- Removing Damaged Ends: If you have split or dead ends, your hair can appear very thin towards the bottom. Cutting these damaged ends off removes the thinnest part of the strand.
- Blunt Cut: A blunt cut across the bottom can create the illusion of fuller, thicker hair compared to wispy or layered ends.
Practical Insight: Getting regular trims to remove split ends is beneficial for maintaining the overall appearance of healthy, fuller hair, even though it doesn't influence growth at the root.
Here's a quick summary:
| Aspect | Effect of Cutting Hair |
|---|---|
| Actual Thickness (Density) | No Change |
| Perceived Thickness | Can Appear Thicker |
So, while the strands themselves don't become wider or more numerous after a cut, the overall look and feel of your hair can improve, giving the impression of increased thickness, especially by removing damage.
