Singed Lashes

Please use a shield or googles.

Lashes will singe if you are too close to bbq, ovens ,fireworks, etc.

Extreme heat will effect all retention. You can swim, sauna, and gym, but stay away from extreme heat.

Greta retention with singe lashes.
These lashes will start to fall out quicker. They will not last. The heat messed up the bond. 
Educate your client what to expect. 
As you can see , there are no space to banana peel, do what’s best, wide skeleton and tell them they will experience a quick fall out. The spine work you created will past them through until the next fill.
Trick: trim every other few single lash to release the sticking together effect. Do not trim blunt across. Tapper them inwards
