You can re-lift your clients lashes/brows after 48hrs if your lift has failed but remember to reassess the hairs and reduce your timings by at least half. If you have over processed the hairs, you should not re-lift as this will only cause more damage to the hairs. Your client should be applying Castor Oil daily.
How long to wait before offering the next Lash Lift or Brow Lamination Treatment. Typically we suggest 4-8 weeks but this really depends on your particular client. The main thing to remember is that you do not want to apply product on already lifted hairs. So if their hairs have grown out enough to apply product on clean, fresh hair, you are good to go! If they would like a re-lift but their hair is still lifted within less than half way up the root of the hairs, this is not recommended as this is what will cause over processing.
