Frequently Asked Questions (FAQs)

1. How long do keratin bonded hair extensions last?

Keratin bonded hair extensions typically last for three to six months. These extensions are delicately attached to your own hair using natural keratin bonds, which expand and contract with water without causing breakage.

2. Do keratin bond extensions damage hair?

Keratin bond extensions can potentially damage hair and scalp if not applied correctly by trained professionals. While they provide volume and fullness, like any beauty treatment, improper application can cause harm.

3. How do you maintain keratin bond hair extensions?

To maintain keratin bond hair extensions, it's important to brush your hair gently, avoid heat styling, sleep with dry hair, avoid chlorine and saltwater, use a leave-in conditioner, be cautious when styling, have regular servicing, and follow proper care instructions.

4. What are the disadvantages of bonded hair extensions?

Bonded hair extensions have some disadvantages, including a long application time of 4 to 8 hours, potential damage to natural hair due to heat and adhesive use, and the need for a highly trained professional to apply them.

5. How much is a full head of keratin bond extensions?

The cost of a full head of keratin bond extensions can range from $800 to $3,000. The final price depends on factors such as the amount of hair used, the desired length, and other considerations unique to each hair extension process.

6. How often should you wash your hair with bonded extensions?

The frequency of washing your hair with bonded extensions varies depending on individual hair types. Generally, it is recommended to wash hair extensions 2-3 times per week to avoid excessive moisture at the roots, which can cause the keratin bonds to soften and potentially lead to shedding or bond loss.

7. What is the most damaging type of extensions?

Among the most damaging types of hair extensions are tape-in hair extensions and micro-link hair extensions. Tape-in extensions involve adhesive application, while micro-link extensions are individual extensions that can also cause damage if not handled properly.
