Problems with retention? One of the most common reasons for bad retention is a poor pre-treatment procedure. If you want eyelash extensions to last longer, natural lashes need to be absolutely free of any traces of oils, sebum, dust or make-up before you begin the lash application. With just a lash cleanser and primer it's not always possible to clean natural lashes up to the excellent standard. If any make-up or oils remain on the natural lashes - retention will be affected.For the best retention, always wash the client's lashes before the treatment with our LASH SHAMPOO / FOAM CLEANSER: Perfectly cleans oil, sebum, make-up and dust from the lashes Can be used for full sets and for infills Antibacterial Tea Tree extract prevents infections and conditions like Stye or Blepharitis.
