The two factors contributing to underarm hair growth

There are two main factors which contribute to the growth of underarm hair. So, why do we grow hair under our arms?

1. Biological factors
   As we grow older, our bodies naturally change, and the same goes for the growth of underarm hair.¹ So, when we ponder the question “Why do we have underarm hair”, it can often be linked to the natural process of transitioning into adulthood.²³
   
2. Hormones
   As you know, we’re not medical experts in this field but it’s known that certain hormones, like androgens, can influence hair growth.4 Conditions such as polycystic ovary syndrome, also known as PCOS, are often linked to higher levels of these hormones which can contribute to increased hair growth.

Why do some individuals choose not to remove underarm hair?

Now you know the answer to the question, “Why do we grow underarm hair”, you’re probably considering what to do about it. Whilst many look for the best way to get rid of underarm hair, some individuals choose to keep it. So, why do some people choose not to remove underarm hair?

• Body temperature
  The hair on our bodies isn’t just for the looks! It actually helps us to stay warm in chilly weather and cool in the heat. So, if you choose to embrace your underarm hair, it’s not just a fashion statement – it could also help you manage your body temperature.⁴
  
• Skin protection
  Traditional hair removal methods such as shaving or waxing can sometimes cause discomfort and skin issues, such as cuts, razor burns, irritation, and ingrown hairs.
• Personal preference
  While some individuals choose to remove underarm hair, many others prefer to keep it due to personal preference and comfort. Ultimately, it’s always a matter of personal choice!
• Avoid dry skin
  Choosing not to remove underarm hair allows you to reduce friction and retain the natural oils produced by your skin. This can help to reduce the risk of your skin drying out.⁵

Benefits of choosing to remove underarm hair

Although you now have several benefits to keeping armpit hair, it is still a personal choice, and many choose to remove it. Before we share the best way to get rid of underarm hair, let’s explore the benefits of choosing to remove underarm hair.

1. Being hair-free means smooth, soft underarm skin.⁶
2. Removing underarm hair can help to reduce body odour.⁷
3. When you have less underarm hair, you sweat less.⁸⁹
4. Choosing the right hair removal method can reduce the risk of ingrown hair, especially if you have curly or coarse hair.

Tips and tricks for the best way to remove underarm hair

Learning how to get rid of underarm hair is simple with our tips and tricks. Here is our guide to 6 methods of how to remove underarm hair:

1. IPL underarm hair removal
   IPL hair removal for underarm hair is becoming increasingly popular thanks to its speed, reduced risk of injuries, irritation, and ingrown hairs, and long-lasting results.
   Top tip: We recommend investing in a good quality product such as the Philips Lumea IPL. Complete with attachments suitable for different parts of the body, this device offers up to 92% hair reduction in just three treatments¹ and six months of ingrown hair-free smooth skin after 12 treatments.²
   
2. Shaving
   This traditional hair removal method is budget-friendly, quick, and easy. It’s important to ensure you use warm water and shaving foam or gel to protect your skin when using this technique.
   Top tip: Care for your sensitive skin with the Philips Lady Shave Series 8000, which offers a comfortable, smooth shave. Plus, 80% of users confirm no redness or razor burns.³
   
3. Waxing
   An extremely common hair removal choice, waxing can be done by a professional or in the comfort of your own home. While it can be painful, waxing on small areas like the underarm is an extremely quick method of hair removal.
   
4. Epilating
   For the best results, epilating your underarms should be done in a downward motion, opposite to the direction of the growth. This ensures the hairs are removed at the root, for longer-lasting results.
   Top tip: If you’re looking for a powerful hair removal device that is gentle on the skin, the Philips Epilator Series 8000 is a great choice. Enjoy up to 4 weeks of smooth, hair-free skin with a treatment that takes as little as 10 minutes.
   
5. Depilatory cream
   If you’re looking for a quick and easy method of hair removal to fit into your busy schedule, depilatory creams are ideal. They only offer short-term results, however, so be prepared to repeat the method regularly.
   Top tip: Always read the label before using these creams to ensure that you protect your skin, and do not leave them on for any longer than advised in the guidelines. Additionally, test these products on a small area of skin before use. This will prevent unwanted adverse reactions on your sensitive underarm skin.
   
6. Electrolysis
   Electrolysis is an expensive and time-consuming hair removal method, but it offers permanent results. This technique targets and fully destroys the hair follicle, ensuring that hair can no longer grow. It can cause a painful stinging sensation, so it’s not for everyone, but for some, it is worth it for the long-term outcome.¹⁰
