Can You Combine LashFixx™ With Tint or Keratin? Here’s What Pros Need to Know

If you’ve just lifted your client’s lashes with London LashFixx™, you might be wondering -  can I follow up with a hybrid dye lash tint? What about a Brow and Lash Doctor keratin treatment?

The answer is yes — and with the right technique and product pairing, you can take your lash lift results from great to glorious.

Here’s everything you need to know about safely combining LashFixx™ with tint or keratin, and why this gentle system is perfect for multi-step treatments.

First, Why Use LashFixx™ as Your Base?

LashFixx™ is a cysteamine-based lash lift system that’s ammonia-free, odour-free, and formulated to gently restructure lashes. Its low-pH, vegan formulation makes it ideal for pairing with other treatments — especially for sensitive clients.

That’s what makes it such a good partner for tints and keratin. Less stress on the lashes = more room for creativity and customisation.

Lash Tint + LashFixx™: What You Need to Know

Yes, you can tint after LashFixx™ — just follow the right order.

Here’s the ideal sequence:

1. Step 1 (Lift) – Apply LashFixx™ Lift Solution

2. Step 2 (Fix) – Apply LashFixx™ Fix Solution

3. Optional: Apply Tint – Right after the fixing step, before keratin  (if using)

4. Step 3 (Nourish or Keratin) – Finish with a keratin serum or conditioning step

💡 Top Tip: Always choose a vegetable-based or semi-permanent tint that’s lash-safe.

Patch test for sensitive clients, especially when pairing treatments.

LashFixx™ + Keratin Treatment: How to Combine Safely

A keratin finish is the cherry on top of a lash lift. It strengthens the lashes, seals the curl, and adds glossy shine.

To combine LashFixx™ with Lash and Brow Doctor or Speed Lift keratin:

• Apply keratin serum as your Step 3

• Use a product designed to nourish and protect the hair shaft, not something overly heavy or oily

• Avoid lash oils for at least 24–48 hours post-treatment

✅ Best For:

Clients with dry or brittle lashes, those prone to breakage, or anyone who wants an extra boost of strength and hydration.

Key Do’s and Don’ts for Combination Treatments

DO:

• Tint after fixing, not before

• Use lash-safe, gentle products

• Keep keratin light and breathable

• Follow proper timing for each step

DON’T:

• Tint before Step 1 — it won’t take properly

• Use strong oxidants alongside a cysteamine system

• Skip patch testing (especially if combining treatments for the first time)

Why LashFixx™ Makes Combining Treatments Easier

Compared to more aggressive formulas, LashFixx™ gives you a wider margin for pairing, without compromising lash health. The gentle restructuring means:

• Less lash dehydration

• Reduced breakage risk

• More consistent tint uptake

That means happier clients, better results, and repeat bookings for you.

Make Lash Lifting Work Harder (and Smarter)

Whether your client wants fuller, darker lashes or just a nourishing finish, LashFixx™ gives you the flexibility to personalise every treatment.
