Here are some considerations:

1. Do your homework. Read up as much information that you can on the various extensions companies and type of hair used. Look at their websites, but don't always believe everything that they tell you. Look for independant comparisons.
2. Ask different hairdressers. If there is anyone who has seen problems with hair extensions then it is a hairdresser. Visit the more expensive salons because you know they will offer the best systems.
3. Assess how long has the company been around for. The tried and tested companies will generally have been around for years. Be wary of the “newest, latest, cheapest”. You may have no recourse if unhappy and the company no longer exists, or is unable to supply extensions anymore.
4. Can you reuse the hair? Take into consideration that some hair extensions can be reused (Great Lengths cannot be reused) A word of caution: Find out how much the salon charges to reinstall the hair. Its never free and often quite expensive.
5. Ask for a few “satisfied clients” for their opinion on the extensions and see if you can see an installation that is over 2 months old.
6. Establish how much will it cost in total. Ask for all of the costs. Installation, removal, shampoo’s, conditioners and cutting. Do not be caught off guard by any hidden costs that were not discussed beforehand. Please be aware that quality hair extensions are expensive, because ethically obtained human hair in pristine condition is expensive to purchase and process. If hair is inexpensive, the you are sacrificing on quality.

7. Find out the differences between the companies? How do they attach the extensions to your own hair? How are they removed? What does the hair feel like? Where does the hair come from? Is the company internationally recognised?
