We recommend brushing Great Lengths three times a day with a Great Lengths paddle brush to prevent tangling at the attachment sites.

Beginning at the nape and working up, brush row by row brushing through the bonds from scalp to ends.

Always keep the direct heat from thermal styling tools, including a blow dryer, a minimum of 1.5” away from the attachment sites (bonds). Otherwise, style as usual.


Return to your Certified Great Lengths Stylist approximately two weeks after your application. This follow-up visit allows the stylist to inspect the application to ensure that your Great Lengths application result is performing as expected.

Always use the Great Lengths Anti-tap Formula after every wet treatment. Mix one ounce (as indicated on the bottle) to 8 ounces of water in the Great Lengths Anti-Tap Spray Bottle. The Anti-tap Formula is designed to neutralize irregularities in your water source and/or to protect the keratin bond polymers from chlorine, saltwater and other solutions not compatible with a proper pH.

To prevent premature bond breakdown and to protect your hair, always saturate your hair with water and apply Great Lengths Anti-tap Formula prior to swimming, exercising, using a sauna or any activity that creates moisture in your hair for an extended period of time. Immediately after such activities, shampoo thoroughly, condition, apply the Anti-tap formula and blow-dry the attachment sites.

Always pull Great Lengths into a softly held ponytail while sleeping and during any activity that has your hair blowing in the wind.

Some extension loss is normal throughout the life of your Great Lengths extension application. The average person experiences natural hair loss of 100 to 150 hairs per day. After some time you can expect to see a small quantity of your hair that has shed naturally yet is still attached to the bond. This is normal and should not be interpreted as hair that has been pulled out of the scalp by the extensions. Daily brushing as instructed will prevent those loose hairs from catching on one another, tangling and potentially matting at the attachment areas.

It is normal to experience some extension loss, over the time you are wearing Great Lengths. 

With that said, it is imperative that you only use Great Lengths and or our Professional JBeverly Hills products.
