Q: Can I blow-dry my hair extensions if they are human hair and glued in?
 
A: In most cases, yes. If your hair extensions are made from real human hair and were applied using a glue method, you can blow-dry them. However, the exact instructions depend on the salon that applied the extensions and the specific adhesive system they used.
 
Many extension methods come with specific care instructions. Adhesives are sensitive to heat. Excessive temperature can soften and weaken the bonds, causing the extensions to detach. Hair salons may recommend particular drying techniques and many will only honor their service guarantee if you strictly follow their recommended aftercare routine.
 
Your first step should always be to contact the salon who applied your extensions. They can tell you how much heat is safe to use and whether there are techniques to avoid.
 
Glued hair extensions
 
As a general rule, glued human hair extensions can be blow-dried safely if you use proper techniques:
 
• Use Low-to-medium Heat: Avoid the highest temperature settings.
 
• Keep the Airflow Moving: Keep the hair-dryer moving rather than concentrating heat on a single spot.
 
• Gently Towel-Dry First: Gently blot (do not rub!) your hair with a towel before blow-drying. This will minimize the total heat exposure time.
 
• Work from Ends to Roots: Focus on drying the lengths and ends first, being extra cautious near the extensions’ attachment points.
 
• Apply Hair Products Carefully: Apply hair products (leave-in conditioners, oils, …) on the mid-lengths and ends only. Never apply oils near the glued bonds. Oils dissolve adhesives!
 
• Avoid Tension: Avoid pulling your hair with a brush while drying. Use an extension loop brush or wide-tooth comb, starting at the ends and working your way up to minimize stress on the attachments.
