Lash Primer ph7 (20ml)
It prepares the surface for a better bond with adhesives and increases retention and extension life.
It can be used as a cleanser to remove any traces of make-up and oils on natural lashes or brows before lash lift or brow lamination procedure.
Not for retail sale, professional use only.
The surface of the eyelashes is naturally acidic (pH ~ 5), which is not optimal for bonding to the polyester extensions with glue. With the help of our primer, you can reach a neutral pH, maximizing glue adhesion.
At pH levels above 7 (alkaline environment), cuticles may peel and get damaged. Also, the glue may shock-cure, which leads to the deterioration of its property.
- A few numbers to remember:
- Hair, skin, nail pH 4.5-5.5 Acidic
- pH 7 Neutral
- Perm colour agent pH 8-10.5 Alkaline
- Straight perming agent pH11.5-14 Strong Alkaline
1 drop per use, about 200 uses.
Gently glide the primer along the eyelashes to cleanse and adjust the pH level.
Make sure the lashes are completely dry before applying eyelash extensions.
Expiry date is marked on the bottom of the bottle.
Dispose within 6 months after opening.

By adjusting the pH level of the natural lashes to pH 7 with this primer, the extension glue sticks tighter and faster and the application procedure is easier.
There are various types of lash cleaners such as alkaline or acidic pH types.
If the natural lashes become alkaline, the cuticles will open easily, which may cause the adhesive to get into the peeled cuticles and make it difficult to provide good retention. Alkalinity also causes the adhesive to shock-cure.
So, I always use this product before procedures to prevent damage and to give better retention.
