Fusion Hair Extensions Pros and Cons

March 06, 2020

As with any type of hair extension method, there are pros and cons.  It is always advised to look at all the different options and their pros and cons before making a decision on which type of hair extension is the best for you.


  • Fusion extensions can give you longer, fuller hair that lasts up to 6 months
  • The bonds are applied close to the scalp which means they can look very natural
  • Unlike some types of hair extensions which use large wefts, the hot fusion extensions can be styled in multiple ways including up-dos and braids.  This is thanks to the way that the strands are small and flexible.


  • The high heat used to melt the bonds can be damaging to the natural hair
  • If the fusion extension bonds are not applied by a certified or extremely experienced technician, there  is a risk of burning the scalp or natural hair
  • They take a long time to apply - due to the application process being so technical it typically can take 4-5 hours for a full head of fusion hair extensions
  • They are expensive and costly to maintain, these hair extensions can not be done at home!  
  • Although the process itself is simple, it also takes a long time.  Each bond has to be soaked in a solution and then cracked apart with a specialist tool to release the hair.  
  • Fusion hair extensions should not be worn for a prolonged period of time as they can cause long term damage and strain on the hair roots.
  • The bonds cannot come into contact with any heated appliances such as straighteners, tongs or hair dryers.
  • With newer, less damaging types of hair extensions, your stylist may suggest you look at other options
