Bonded hair extensions are some of the most popular types on the market. But there are various forms to consider.

‘Flat tip extensions are a professional hair extension method. They're flexible, comfortable to wear and virtually undetectable with any hairstyle. The keratin bonds are resilient against heat and water and designed for durability yet gentle on the hair,’ explains Nicole Petty, Haircare Expert for Milk + Blush. .

‘Flat-tip hair extensions are by far the most discreet, longest-lasting hair and lowest maintenance extensions currently available,' says Nicole, 'you must also be prepared to regularly brush your hair throughout the day to avoid tangles, as well as limit the amount you wash your hair. Once a week is ideal.’

‘Then there's Nano tip extensions, which are a pre-bonded method that allow clients to achieve long-lasting results without using heat or glues.’

Nano tip extensions are a heatless method, where natural hair is simply threaded through a nano ring at the tip of the nano extension before being clamped into place. This application method reduces the risk of damage to natural hair, making it a popular extension choice.’

‘Tape-ins are one of the most popular styles of semi-permanent extensions and can suit almost any hair type,’ explains Nicole.

‘They are incredibly lightweight and the least likely to pull hair, making them one of the least damaging hair extensions on the market. However, costly maintenance appointments (usually every six to eight weeks), could put off those not prepared to commit to the investment.‘

‘A weave is another permanent method of applying hair extensions which generally involves gluing or sewing a piece of hair onto your natural hair braided flat against your scalp,' says Nicole.

‘On the pricier side of the extension options - weaves last for around six to eight weeks and require expert installation to ensure they aren't pulling on your scalp.’

‘However, people with weaves should be careful not to wash them too often,' Nicole continues, 'as this can loosen the braid base and cause the weave to slip down.’

‘Clip-in extensions are the cheapest option, giving wearers plenty of versatility over when and how they wear extensions,’ says Nicole. ‘Plus, they are great for adding a bit of extra volume and length to your hair without the commitment or damage of more permanent options.’

‘But they may not be convenient for those that want to wear extensions every day and can be trickier to blend without the help of a stylist.’

Kim Kardashian recently shared a TikTok showing her natural hair, which looks noticeably finer than the locks we're used to seeing. Since then, Google searches for "do hair extensions damage hair" has seen a huge 9,100% uplift.

While historically, extensions got a bad rep for damaging hair, these days most types of extensions shouldn't cause any damage if you've locked down a good pro and your aftercare is hitting the mark. The key to keeping your hair healthy? Always get a professional to apply them. Follow the proper aftercare guidance and you choose the correct style for your hair type and lifestyle.

'If you're concerned about hair health, start with non-permanent options, such as clip-ins,' suggests Nicole.

'A lighter-weight set will comfortably give you temporary length and volume while allowing your head and neck a break from the additional weight.'

‘Whether you are a regular extension wearer and are in between appointments, or you’re a first timer, the key to ensuring your extensions don't cause damage is to get your natural hair in good shape,’ says Brenda Lee Intignano, extensions and trend expert from Cliphair. ‘Ideally, your natural hair should be smooth and not brittle, so try and give your hair intensive conditioning treatments in the lead-up to applying your extensions. Also as a rule of thumb, you should avoid heat tools and anything that dries your strands out, as these can cause breakage.

Right before either your salon appointment, or before you apply your extensions yourself, your hair should be freshly washed, dried and completely free from tangles.’

‘Depending on the type of extensions you opt for, you may or may not need to visit a professional. If you are looking for a quick transformation and don't plan on wearing extensions for a long period of time, then clip-in hair extensions are the best and easiest choice. Clip-ins are one of the most popular types of extensions as they allow wearers to clip them in and out, easily and comfortably.

If you would prefer longer-lasting extensions, tape-in hair extensions or nano ring extensions are both great options.’

'These days, most extensions are made of human hair, and use a keratin bond or a medical grade tape, so that they allow you to wash and shampoo your hair like normal,' explains celebrity hair stylist and extension expert Hadley Yates, who uses Great Lengths extensions at his London salon.

'You should always use a sulphate free shampoo to protect your extensions. Most extension brands will have a recommended product range or you can always ask your stylist to recommended what they think would suit your hair needs best.'

‘Perhaps an overlooked step in your new haircare routine, you must ensure you brush your hair carefully,’ advises Brenda. ‘Be wary not to brush your hair or extensions too harshly and instead lighten your hand. Start brushing in a downward motion at the end of your hair, with your free hand holding the hair firmly at the attachment points to avoid tugging or straining. Slowly work your way up towards the roots, making sure you only brush in a downward motion.’

'How long your extensions will last largely depends on which extension method you use,' explains Hadley Yates. 'For bonds, I’d recommend keeping them in for no longer than 4 months. This is because your natural hair will still shed around the bond and it will become harder to maintain your look once they’ve grown down. For tape-in extensions, you should keep them in for no longer than 8 weeks, as otherwise they’ll start to twist.'
