Has it ever happened to you that after shaving or waxing, your skin itches like crazy when the hair begins to grow back? You’re not alone. This phenomenon is quite common. So, why does it happen? In this article, we’ll answer that question and dive deep into the causes of itching during hair growth. We’ll also explore some natural remedies to soothe that irritating itch. Let’s get started.
The Science Behind Hair Growth and Itching
Every hair on our body grows out of a hair follicle. The hair growth process has three stages – anagen, catagen, and telogen. The anagen phase is the active growth stage, where the hair follicle produces new hair cells. The catagen phase is the transitional phase, where hair growth slows down, and the follicle shrinks. Finally, the telogen phase is the resting phase, where the hair falls out, and the follicle remains inactive for a while.
Our body views the formation of a new hair as a foreign object, and the immune system responds by sending white blood cells and histamines to the affected area. Histamines cause itching, and that’s why we feel the urge to scratch the skin when hair grows back.
Interestingly, hair growth is influenced by various factors such as genetics, age, hormones, and nutrition. For instance, hormonal changes during pregnancy can cause hair to grow thicker and faster, while aging can lead to hair thinning and loss. Additionally, a diet lacking in essential nutrients like protein, iron, and vitamins can affect hair growth and lead to hair loss.
Moreover, excessive scratching due to hair growth can cause damage to the skin and hair follicles, leading to inflammation, infection, and scarring. It is important to resist the urge to scratch and instead use gentle hair care products and techniques to promote healthy hair growth and prevent itching.
Understanding the Hair Growth Cycle
To understand why hair growth causes itching, it’s essential to understand the hair growth cycle. As mentioned earlier, hair growth has three stages – anagen, catagen, and telogen. The anagen phase is the most crucial phase of hair growth because it determines the length and thickness of the hair.
During this stage, the hair follicle is actively producing hair cells, which push out towards the surface of the skin. As new hair cells form, the old, dead cells are pushed out, resulting in hair growth. The hair growth rate is around 1/2 inch per month on average. Different areas of the body have different growth rates, with scalp hair growing the fastest.
The catagen phase is the transitional phase of hair growth, where the hair follicle shrinks and detaches from the blood supply. This phase lasts for about two weeks, and the hair growth stops during this time. Finally, the telogen phase is the resting phase of hair growth, where the hair follicle remains dormant for about three months before shedding the old hair and starting the cycle again. It’s important to note that not all hair follicles are in the same phase at the same time, which is why we don’t shed all our hair at once.
The Role of Nerves in Hair Growth Itching
Nerves also play a significant role in itching during hair growth. When a hair follicle produces a new hair, it activates receptors in the skin called C fibers. These C fibers send signals to the spinal cord and brain, which results in the sensation of itching.
When we scratch our skin, it further stimulates the C fibers, leading to more itching. Scratching can also cause tiny micro-tears in the skin that can lead to bacterial infections and inflammation.
Interestingly, some studies have shown that stress can also contribute to hair growth itching. When we are stressed, our bodies release certain chemicals that can activate the C fibers and cause itching. This is why some people may experience more itching during periods of high stress.
How Shaving Affects Hair Growth and Itching
Shaving is one of the most common methods of hair removal. However, it can also cause itching when hair starts to grow back. The reason for this is that shaving cuts the hair at the surface of the skin, leaving a sharp edge that can curl back and penetrate the skin. This, in turn, triggers an immune system response and causes itching.
Shaving also irritates the skin, which leads to dryness and further itching. It’s crucial to use a sharp razor and shaving cream or gel to minimize skin irritation during shaving. Using a moisturizer after shaving can also help restore the skin’s natural moisture barrier.
Another factor that affects hair growth after shaving is the thickness and coarseness of the hair. Thicker and coarser hair tends to grow back faster and may cause more itching and irritation. In contrast, finer hair may take longer to grow back and cause less discomfort.
It’s also important to note that shaving does not affect the rate of hair growth. Contrary to popular belief, shaving does not make hair grow back thicker or darker. Instead, it only affects the appearance of hair by cutting it at the surface of the skin.
The Connection Between Dry Skin and Itching During Hair Growth
Dry skin can exacerbate itching during hair growth. As we age, our skin loses its natural oils, which can cause dryness and flakiness. Using harsh soaps and hot water can further strip the skin of its natural oils, leading to dryness and irritation.
It’s essential to keep the skin moisturized to prevent itching during hair growth. Using a good quality moisturizer can help restore the skin’s moisture barrier and prevent itching.
In addition to using moisturizers, there are other steps you can take to prevent dry skin and itching during hair growth. One of the most effective ways is to avoid taking long, hot showers or baths. Hot water can strip the skin of its natural oils, leading to dryness and irritation. Instead, opt for lukewarm water and limit your shower or bath time to no more than 10-15 minutes.
You can also try using a humidifier in your home to add moisture to the air. This can help prevent dry skin and itching during hair growth, especially during the winter months when the air is drier. Additionally, wearing loose-fitting clothing made from breathable fabrics can help prevent irritation and itching caused by friction between the skin and clothing.
Effective Ways to Relieve Itching When Hair Grows Back
If you’re prone to itching when hair grows back, here are some effective ways to relieve the discomfort:
- Apply a cold compress to the affected area to reduce inflammation and itching.
- Use a moisturizer containing ingredients such as aloe vera, coconut oil, or oatmeal to soothe the skin and prevent dryness.
- Avoid scratching the affected area as it can cause further irritation and damage to the skin.
- Take an antihistamine to reduce itching caused by the immune system response.
- Use a hydrocortisone cream or gel to reduce inflammation and itching.
Another effective way to relieve itching when hair grows back is to exfoliate the skin regularly. This helps to remove dead skin cells and prevent ingrown hairs, which can cause itching and discomfort. You can use a gentle exfoliating scrub or a dry brush to exfoliate the skin.
In addition, wearing loose-fitting clothing made from breathable fabrics such as cotton can help to reduce itching. Tight clothing can cause friction and irritation, which can exacerbate itching. It’s also important to avoid using harsh chemicals or fragrances on the affected area, as these can further irritate the skin.

If you’re experiencing itching on your scalp during hair regrowth, here are some natural remedies that can provide relief:
- Apply a mixture of tea tree oil and coconut oil to your scalp. Tea tree oil has antibacterial and anti-inflammatory properties that can soothe the skin and prevent infections.
- Apply aloe vera gel to your scalp. Aloe vera is known for its skin-soothing properties and can help reduce itching and inflammation on the scalp.
- Apply apple cider vinegar to your scalp. Apple cider vinegar has antibacterial and anti-inflammatory properties that can help soothe the scalp and prevent itchy sensations.
- Apply a warm compress to your scalp to improve blood circulation and reduce inflammation.
- Massage your scalp with essential oils such as peppermint, lavender, and rosemary. These oils have cooling and soothing properties that can help alleviate itching and irritation.
In addition to these natural remedies, it’s important to maintain a healthy diet and lifestyle to promote hair growth and scalp health. Eating a balanced diet rich in vitamins and minerals, such as iron, zinc, and biotin, can help strengthen hair and reduce scalp irritation.
It’s also important to avoid using harsh chemicals and styling products on your hair during the regrowth process. These products can further irritate the scalp and slow down the hair growth process. Opt for gentle, natural hair care products and avoid using heat styling tools as much as possible.
