Does Hair Grow Back Thicker After Shaving

The idea that shaving makes your hair grow back thicker, darker or faster has been around for generations. Many of us have heard this claim from family members or picked it up from conversations, but is there any truth to it? Whether you shave your legs, face or any other part of your body, you might be wondering if this popular myth has any basis in science. In this article, we’ll explore what really happens to your hair after shaving and what it means for your hair growth and appearance.

Understanding the Hair Growth Cycle

To understand why this myth persists, it helps to know how hair actually grows. Each hair on your body goes through a natural cycle consisting of three main phases. The anagen phase is when hair actively grows from the root. The catagen phase is a short transitional period where growth slows, and the telogen phase is when the hair rests and eventually falls out. A new hair then grows in its place.

Shaving only removes hair at the surface of the skin. It has no effect on the hair follicle, which is where growth happens. This is why shaving does not influence the speed, colour or thickness of new hair. What you are doing is trimming the part of the hair shaft that has already emerged, not changing anything deeper in the skin.

Why Shaved Hair Feels Thicker

One of the main reasons people believe hair grows back thicker after shaving is because of how the regrowth feels. Shaving cuts the hair straight across, creating a blunt edge. As the hair grows out, this blunt tip can feel coarser or stubbly, especially when touched. This texture can give the illusion of thicker hair, but the diameter and colour of the hair remain the same as before.

Additionally, newly grown hair may appear darker or more noticeable because it has not yet been exposed to sunlight or environmental wear. Sunlight can naturally lighten hair, and over time, hairs become tapered at the ends through friction and weathering. Fresh regrowth looks more prominent simply because it is new, not because shaving has altered its structure.

Does Shaving Increase Hair Growth?

There is no scientific evidence that shaving increases the rate of hair growth. The number of hair follicles you have is determined by genetics and hormones, and shaving does not stimulate more follicles to grow or produce hair more quickly. In fact, if shaving were a way to grow thicker hair, it would likely be a recommended treatment for thinning hair or hair loss, which it is not.

Hair growth is more heavily influenced by internal factors such as hormonal changes, health conditions, age and even diet. For example, during puberty or pregnancy, hormone shifts can cause hair to grow faster or become coarser. Similarly, poor nutrition or certain medical conditions can slow growth or lead to thinning.

Hair Thickness, Hormones and Ageing

If you have noticed a change in your hair’s thickness over time, it is likely related to hormonal fluctuations or the natural ageing process. Testosterone, oestrogen and other hormones play a major role in how hair grows, particularly in areas like the face and scalp. With age, hair may become finer, grow more slowly or fall out more easily. These changes happen regardless of whether you shave.

Men and women both experience changes in hair density as they get older, and it is completely normal for hair to behave differently over the years. While shaving can affect how hair feels temporarily, it does not influence the actual properties of the hair strand itself or its underlying root.

Caring for Hair and Skin Post-Shaving

While shaving does not affect hair thickness, it can impact the skin. Using a clean, sharp razor and shaving with a hydrating cream or gel can help reduce irritation and minimise nicks or bumps. Moisturising after shaving is also a good habit, especially on sensitive areas like the face or legs. Taking care of the skin helps support overall comfort and can reduce the risk of ingrown hairs, which can sometimes mimic the appearance of thicker regrowth.

You may also consider exfoliating between shaves to keep the skin smooth and reduce the build-up of dead skin cells. This can help hairs grow out more freely and prevent them from becoming trapped beneath the surface.

The Role of Collagen in Hair and Skin Health

While shaving does not directly affect hair thickness, some people look for ways to support healthier-looking hair and skin from the inside out. Collagen, a naturally occurring protein in the body, plays a key role in maintaining the strength and elasticity of the skin, including the scalp and hair follicles. As collagen levels decline with age, this can affect the condition of your hair and skin.

Taking a collagen supplement may help support skin hydration and resilience, and it could be a helpful addition to your wellness routine if you are aiming for a healthy glow or stronger-feeling hair. Although collagen does not directly make hair grow faster or thicker, it can be part of a balanced approach to beauty and ageing.
