Does Running A Needle Through Your Hair Sharpen It?

If you have dull, lifeless hair you may wonder if simply running a needle through the strands could sharpen and revitalize your locks. This unusual hair trick has intrigued many people looking for an easy DIY solution to get salon-quality hair at home.

If you’re short on time, here’s a quick answer to your question: Running a needle through each strand can remove split ends and give the appearance of thicker, healthier hair. However, it does not truly ‘sharpen’ the hair.

In this comprehensive guide, we will look at the science behind this needle trick, its risks and benefits, proper technique, and alternatives for conditioning and volumizing hair.

The Science Behind the Needle Trick

Have you ever heard the trick of running a needle through your hair to sharpen it? While it may sound like an old wives’ tale, there is actually some science behind it. Let’s take a closer look at the phenomenon and understand how it works.

How Hair Splits

Before we dive into the needle trick, it’s important to understand why hair splits in the first place. Hair is made up of a protein called keratin, which gives it its strength and structure. Over time, exposure to various factors such as heat, chemicals, and even everyday activities like brushing and styling can weaken the hair shaft, causing it to develop split ends.

When the hair shaft weakens, the protective outer layer called the cuticle starts to fray, exposing the inner cortex of the hair. This is what we commonly refer to as split ends. If left untreated, split ends can travel up the hair shaft, causing further damage and making the hair appear dull and frizzy.

Removing Split Ends

Now, let’s get back to the needle trick. The idea behind running a needle through your hair is to remove the split ends. By inserting a needle through a strand of hair, you can catch and cut off any split ends that protrude from the shaft.

However, it’s important to note that this trick is not a permanent solution. While it may temporarily remove split ends, it does not prevent new ones from forming. Regular haircuts and proper hair care practices, such as using heat protectants and avoiding excessive heat styling, are still necessary to maintain healthy hair.

Potential Risks of Damaging Hair

While the needle trick may seem like a quick fix for split ends, there are some potential risks involved. If not done carefully, running a needle through your hair can lead to further damage. Improper technique or excessive force can cause breakage or even cut the hair shaft, resulting in more split ends.

It’s also worth mentioning that using a needle on your hair can be unhygienic and potentially harmful. The needle may carry bacteria or cause puncture wounds if mishandled. It’s always best to consult a professional hairstylist for proper hair care and maintenance.

Step-By-Step Technique for the Needle Trick

Gather Supplies

Before attempting the needle trick, it is important to gather all the necessary supplies. You will need a sewing needle, preferably one with a sharp point, and a comb or brush to help separate your hair into sections.

Additionally, it is recommended to have a towel or cloth nearby to wipe off any excess oil or residue from the needle.

Work on Small Sections

Once you have all your supplies ready, it’s time to start working on your hair. Begin by dividing your hair into small sections. This will make it easier to run the needle through each strand and ensure that the sharpening process is evenly distributed.

Run Needle from Tip to Root

Take a small section of hair and hold it taut between your fingers. Carefully insert the sharp end of the needle into the hair, starting from the tip and moving towards the root. Be gentle and take your time to avoid any unnecessary tugging or pulling.

Tip: It’s important to note that running a needle through your hair does not actually sharpen it. This is merely a trick or optical illusion that can create the appearance of sharper hair strands.

Repeat on All Sections

Continue running the needle through each small section of hair until you have covered your entire head. Remember to be patient and take breaks if needed, as this process can be time-consuming.

Finish with Conditioner

Once you have completed the needle trick, it is recommended to finish off with a nourishing conditioner. This will help restore any moisture that may have been lost during the process and leave your hair feeling soft and manageable.

Benefits and Drawbacks of Using a Needle on Hair

Pros: Removes splits, Adds Volume

Using a needle on hair can have several benefits. One of the main advantages is that it helps in removing split ends. Split ends occur when the protective outer layer of the hair cuticle gets damaged, causing the hair to split into two or more strands.

By carefully running a needle through the hair, split ends can be individually snipped off, promoting healthier hair growth and preventing further damage. This technique is particularly useful for those who want to maintain long hair without sacrificing its overall health and appearance.

In addition to removing split ends, using a needle on hair can also add volume to the hair. By gently teasing the hair with the needle, it creates small knots that give the illusion of fuller and thicker hair.

This technique is commonly used in hairstyling to achieve a more voluminous look without the need for excessive teasing or the use of volumizing products.

Cons: Potential Hair Breakage, Very Time Consuming

While using a needle on hair can have its benefits, it is important to be aware of the potential drawbacks. One of the main concerns is the possibility of hair breakage. Running a needle through the hair, especially if done forcefully or too frequently, can cause hair strands to weaken and break.

It is crucial to be gentle and cautious when using this technique to minimize the risk of hair breakage.

Another drawback of using a needle on hair is that it can be a time-consuming process. The precision required to individually remove split ends or create volume knots can take a significant amount of time, especially for those with long or thick hair.

It is important to consider whether the time investment is worth the desired outcome.

It is worth mentioning that while some individuals may find success in using a needle on their hair, it is not a widely recommended or scientifically proven method. It is always best to consult with a professional hairstylist or trichologist for personalized advice and alternatives that are backed by research and experience.

Alternatives for Smooth, Shiny Hair

Having smooth and shiny hair is a desire shared by many. While running a needle through your hair might not be a recommended solution, there are several alternatives that can help you achieve the desired results.

Whether you have frizzy, dull, or damaged hair, there are various treatments and products available to give your locks a healthy and lustrous appearance.

Deep Conditioning Treatments

Deep conditioning treatments are a great way to nourish and hydrate your hair from within. These treatments typically involve applying a rich, nutrient-packed conditioner to your hair and leaving it on for an extended period of time.

This allows the ingredients to penetrate the hair shaft, repairing damage and providing much-needed moisture. Regular deep conditioning can help restore shine and smoothness to your hair, leaving it looking healthy and vibrant.

Leave-In Conditioners

If you’re looking for a quick and easy way to improve the texture and appearance of your hair, leave-in conditioners are a fantastic option. These lightweight formulas are designed to be applied to damp hair and left in without rinsing.

They provide an extra boost of hydration and help to detangle and soften the hair, making it more manageable and less prone to frizz. Leave-in conditioners can also help protect your hair from heat styling and environmental damage.

Hair Oils and Serums

Hair oils and serums are another popular choice for achieving smooth, shiny hair. These products are typically applied to the ends of the hair to add moisture and prevent split ends. They also help to smooth down the hair cuticle, reducing frizz and creating a sleeker appearance.

Hair oils and serums come in a variety of formulas, from lightweight oils to silicone-based serums, so you can choose the one that works best for your hair type and needs.

Professional Trims and Keratin Treatments

Regular trims are essential for maintaining healthy hair, as they help to prevent split ends and breakage. By getting rid of damaged and dry ends, you can improve the overall appearance and feel of your hair.

Additionally, if you’re looking for a longer-lasting solution, keratin treatments can be a game-changer. These treatments involve applying a keratin-infused solution to the hair and then sealing it in with heat. The result is smoother, more manageable hair that lasts for several weeks.

Remember, while these alternatives can help improve the look and feel of your hair, it’s important to also practice good hair care habits. This includes using heat protectant sprays when styling with heat tools, avoiding excessive brushing or combing, and using gentle hair ties that won’t cause breakage.

By incorporating these alternatives and maintaining a consistent hair care routine, you can achieve the smooth and shiny hair you’ve always wanted.


While running a needle through hair will remove split ends and can give the appearance of thicker, sharper strands, it does not truly alter the hair structure. Taking proper precautions, this trick can provide some temporary benefits between salon visits but has risks of damaging hair if not done properly.

For longer lasting hydration and shine, deep conditioning treatments and professional services like trims and keratin smoothing provide safer and more effective solutions for revitalizing dull, lifeless hair.
