How to Know When Your Lash Lift is Ready: The Flex Check Explained

Timing is crucial while undergoing lash lift therapy. If you leave the solution on for too long, you run the danger of over-processing; if you remove it too soon, your client may leave with lashes that aren't as lifted. So how do lash technicians know when to take off the solution? This is when the flex check is useful.

To consistently achieve flawless, raised lashes, it is crucial to comprehend the flex check, regardless of your level of experience as a lash artist or your interest in the inner workings of a professional lash lift.

What is a Flex Check in a Lash Lift? 

During the lash lift procedure, the flex check is a method used to determine whether the lashes have sufficiently processed to maintain their new form. You can determine if the lashes are ready for the following stage or whether they require extra time by doing a light flex test after the perm solution has been on them for a few minutes.

The reason it's termed a 'flex check' is because you're assessing the lashes' bounce and flexibility to determine whether the hair structure has altered and softened enough to support a curl. 

How to Perform a Flex Check

The majority of lash artists do it like this:

Hold off until the processing time is almost over: Don't jump right in. Wait at least 8 to 9 minutes before inspecting if you're using a 10-minute perm solution.

• Use a Clean Tool: The ideal tools for this are a microbrush or lash lift tool.
• Gently Nudge a Lash: Gently lift a lash and watch how it responds.
• What you're trying to find:
• The lash is probably ready if it bends readily and feels soft and supple.
• More time is required if it still snaps back or feels rigid.

For lashes, it's similar to checking pasta while cooking: you're trying to find that "al dente" moment. 

Why Flex Checking Matters

It's like flying blind if you skip a flex check. This is why it's important:

• Avoids Overprocessing: Prolonged use of perm lotion can make lashes brittle or even break.
• Prevents Underprocessing: If the solution is removed too soon, the lift will be weak and short-lived.
• Customises Each Lift: Each customer has a unique type of lashes. While coarse lashes may require twelve minutes, fine lashes may just require five. Flex checking makes it easier to customise the time for every customer. 

Tips for Better Lash Lift Results

• Recognise Your Lash Types: Processing time is longer for coarser, thicker lashes than for delicate, finer ones.
• Work With High-Quality Products: Make use of reputable lash lift companies that offer precise timing instructions.
• Use Shields Correctly: Even curl and processing are guaranteed when shields are positioned correctly.
• Don't Ignore the Test: A 5-second flex check might prevent a disgruntled customer. 

Common Lash Lift Flex Check Mistakes

• Checking Too Soon: Prior to testing, always give the solution a reasonable amount of time to function.
• Rough Handling: Exercise caution while you are working with sensitive hair close to the eyes.
• Not Changing Timing Based on Outcomes: If the lashes aren't ready, leave the solution on for a minute or two more, but continue to check at one-minute intervals. 

Although it may appear to be a minor stage in the lash lift procedure, the flex check is revolutionary. It helps guarantee that lashes are processed exactly the appropriate amount—neither too little nor too much. Consider it your go-to tool for dependably perfect lash lift outcomes.

Therefore, the next time you're in the middle of a treatment, pay attention to the lashes rather than the time. Give your clients the boost they deserve by doing the flex check.
