Which Product Should I Use for Prepping My Clients’ Lashes Before Lash Extensions?

When it comes to achieving long-lasting lash extensions, prepping your client's natural lashes is a critical step. 

A classic question…
“Which product should I use for prepping my client’s lashes before lash extensions— Lash primer or Lash Neutral (lash pH balancer)?”

The short answer? It depends on the client's lashes.

In this post, we’ll break down:

• The difference between lash primer and lash pH balancer

• When to use a pH Balancer (Lash Neutral)

• Whether you can use both products together

Lash Primer vs Lash pH Balancer: What’s the Difference?

Both products are used to prepare natural lashes before eyelash extensions, but they serve different purposes:

What Is a Lash Neutral?

Lash Neutral (Lash pH balancer) is designed to:

• Neutralize residue from lash shampoo

• Gently cleanse the lashes

• Promote stronger adhesive bonds

Lash Neutral can be used on clients with:

• Sensitive eyes or lashes

• Lashes that are already clean but need an extra retention boost

• Can be used on anyone
  
  

What Is Lash Primer?

A Lash Primer helps to:

• Remove oil, dust, makeup residue, and proteins

• Dehydrate the lashes slightly, allowing the adhesive to bond faster

• Create a clean surface for optimal lash extension retention

It’s ideal for clients with:

• Oily lashes or skin

• Lash retention issues

Can I Use Both Lash Primer and Lash Neutral?

Short answer, no.
