Who Should Get Bonded Hair Extensions?

Everyone can get keratin-bonded extensions. Candidates for keratin hair extension wearers usually seek longer and thicker hair.

Ryan Trygstad, a celebrity hairstylist, says, “Extensions come in so many textures now to match any wave pattern, which is how they look so natural.

With dense hair, you may need to add a little more strands to match the texture, whereas, with thinner hair texture, a little goes a long way.” (3)

People can instantly revamp their look and style when they bond their natural hair with keratin bonds.

Because of its nature, keratin pre-bonded extensions work on all hair types regardless of length and texture.

How Much Do Keratin Hair Extensions Cost?

The cost of keratin hair can run high since these types of extensions are the highest quality extensions you can find.

Kristina Noto, the extensions specialist at New York’s Warren-Tricomi salon, says:

“Quality extensions can vary in price depending on the desired end result, but adding a few pieces for fullness (usually a half head) should start at $500 and go up to $1,500 at a high-end salon.” (4)

Depending on your hair and the final look you wish to achieve, hot fusion extensions can cost anywhere from $1500 to $4000.

Experienced stylists advise customers to avoid cheaper u-tip hair extensions. Usually, you get what you pay for. This type of extension runs costly.

How Do You Take Care Of Keratin Bond Extensions?

Keratin hair extensions are gorgeous and add tons of volume to the layers of hair. But they require some maintenance if you want the beautiful style to last.

If you are one of those people who shower and forget all about your hair, then this hair extension type is probably not right for you.

Here are some essential care tips on how you can take care of your human hair extensions.

1. Use mild hair shampoos:

You’ll never have a bad hair day ever again with your permanent extensions if you use a mild shampoo without harsh chemicals to clean your hair.

Be gentle on the scalp so you aren’t matting or breaking any bonds. It is best not to over-scrub the scalp.

Also, make sure to deep condition the hair extension bonds to help them last longer.

2. Detangle daily:

It would be best to have a wide-toothed shower comb to run through your hair regularly.


Celebrity hairstylist Jen Atkins shares the importance of brushing regularly with a special brush, like her favorite, the Sheila Stotts extensions brush. (5)

But be sure not to yank at your hair extension bonds, or you will break them loose and lose some hair.

Be gentle, and your hair should do the rest. Ryan Trygstad says, “If you’re hurting your hair, you’ll hurt the extensions, and just cause more damage to your hair all around.” (3)

3. Always dry the hair:

Whether you’re just stepping out of the pool after a good dunk or washing your hair, make sure you dry your hair.

Wet extensions can mat, and the bonds can break when wet for a long time.

Even if you don’t want to use a dryer on your natural hair, dry the extensions, especially around the bonds.

4. Steer clear from hot tools:

This is easier said than done, but avoid exposing the keratin bonds to direct heat. Too much heat can damage its hair follicles.

Also, while using styling tools, do not apply heat directly on the bonds, as that will loosen the bond and cause the hair to fall off.

With special care, you won’t need as many maintenance appointments to keep your hair looking intact.
