Traction Alopecia can be caused by a constant pulling of the hair follicle, causing the body to attack its own hair follicles and make their re-growth unpredictable. Often it can lead to complete hair-loss.

In the eyelash extension world this condition would be caused by too much strain on the natural lash follicle from overweighted lash extensions, clients repetitively pulling at their extensions and stickies (extensions glued together). 

To avoid causing Traction Alopecia on your clients it is extremely important to always assess the natural lashes health before you place extensions on them.

A good guide to what thickness or diameter (ie 0.18, 0.15 or in volume 0.07, 0.05 etc) for each client, is to choose a thickness that is the same or slightly less or slightly more as the clients natural lash.

For example if you were placing volume 4D 0.07 on your clients lashes, then the base of that fan should measure approximately the same as the clients natural lashes.

Or if you were doing a classic set, then your 0.18 should be approximately the same thickness as the clients natural lashes.

Following the “Only  2-4 mm longer than the natural lash” rule in both classic and volume sets.

We have a great blog on how to handle clients who want long lashes: #35 A Client that demands 'Long Lashes'.


It is not uncommon for clients to pick and pull at their extension between appointments. The only way that you can handle this as their technician is to educate them not too. Show them this blog … that should do the trick!

And lastly stickies - when extensions (both classic and volume) are not individually applied and glued. This is entirely the technicians responsibility to ensure they are all individually applied and no stickies are on any set.

It happens to all of us - however a good technician always checks their work and handle any stickies before finishing up the set. (The photo below is way more than just a few stickies by the way).
