Lash lift aftercare, brow lamination care and mistakes

Course: Lash lift and brow lamination course from A to Z · Module 8 of 8

A great result can be lost in the first few hours if the client doesn’t know how to look after it, and repeating a service too soon can ruin healthy lashes. In this final module we cover lash lift aftercare and brow lamination aftercare, how often the treatments can be repeated, and how to recognise, prevent and handle the most common problems: over-processing, uneven curl and brittle, damaged hair.

Module objectives

Give clients clear aftercare instructions for lashes and brows.
Explain how long results last and a sensible interval between sessions, linked to the hair growth cycle.
Recognise the signs of over- and under-processing.
Identify what causes uneven curl and damaged hair, and how to prevent it.
Know when a treatment should not be repeated.

Lash lift aftercare

Guidance varies between manufacturers, particularly on water. Here is what two of the brands we reviewed say:

Topic	Elleebana	Lashbase
Water	Avoid water and steam for the first 24–48 hours (showers, baths, swimming, saunas)	Lashes can get wet; for about 4 hours keep its serum on and let natural oils return
Sauna and steam	Avoid for 24–48 hours	Avoid for 48 hours
Make-up and skincare	Avoid most products (shampoo, creams, face wash, mascara) for 24–48 hours	Not specified
Sleeping	Don’t sleep face-down: pressure can change the lashes’ direction	Avoid sleeping on the face, especially the first night
Rubbing	Don’t rub the eyes	Don’t rub the eyes
Afterwards	Avoid oil-based products	A lash serum for strength and retention

As you can see, there’s no single rule. Give the client the aftercare from the manufacturer of the product you used, in writing, and where it’s silent on something, go with the more cautious advice. If the system includes a nourishing treatment for home use, explain how and when to use it according to its instructions. You’ll find nourishing steps in our lamination category.

Brow lamination aftercare

Keep brows dry for the first 24 hours: Lashbase, Ellisons and Sencha Skin agree (no hot showers, baths, swimming, saunas or steam).
Don’t touch or rub the brows during those 24 hours, so the hairs stay in place (Lashbase, Ellisons).
No make-up, actives or self-tan on the brows for at least 24 hours (Sencha Skin). London Brow Company adds avoiding aggressive treatments and hot environments for 24 hours, and keeping lotions, toners and creams off the area.
Brush daily: after 24 hours, brush the brows into place while damp, for example after a shower (Lashbase, Ellisons, London Brow Company).
Condition between appointments with a brow gel or conditioning serum (Lashbase, Ellisons).

A disposable spoolie from our accessories is an easy thing to send the client home with, along with a quick demo of how to brush her brows.

Always include this in your written aftercare: if intense itching, swelling, pain or increasing redness appears in the following hours or days, see a healthcare professional. Allergic reactions can be delayed; the NHS notes that symptoms from dyes can take up to 72 hours to appear.

How long results last and how often to repeat

Why the result isn’t permanent

A lift or lamination changes the hair that’s already there, not the hair still to grow. According to Aumond and Bitton’s 2018 review, the eyelash growth (anagen) phase lasts four to ten weeks, the complete cycle four to eleven months, and a lash grows around 0.12–0.14 mm a day. As treated lashes shed and new ones come through, the effect fades gradually.

Service	Duration given by sources	Frequency
Lash lift	6–8 weeks (Elleebana)	Lashbase: wait around 6–8 weeks before another full lift; never repeat it a week after the original
InLei Lash Filler protocol	About 5 weeks, up to 2 months for some clients (InLei)	Three treatments 4–6 weeks apart; series repeated 2–3 times a year (InLei’s own protocol)
Brow lamination	Up to 6 weeks (Lashbase, Ellisons); 6–8 weeks (Sencha Skin)	We found no common verified interval; assess the hair and follow the manufacturer

How long it lasts depends on aftercare, each person’s growth cycle and their routine. Reassess before every new session: if the lashes or brow hairs show signs of damage, don’t repeat.

Common problems and how to avoid them

Over-processing

This happens when the reducing lotion works for longer than the lash can take. Signs described by the sources: an excessive, unnatural curl, tips curling back towards the lid, breakage along the lash line, a straw-like texture and lashes that look thin, weak or fragile (Elleebana, Lash Jungle).

Typical causes and prevention:

Too long, or another brand’s chart: use your product’s instructions, start at the minimum and do a flex check.
Lotion on the tips: they’re finer and soften sooner; respect the application zone.
Too much product: more product processes faster (Lash Jungle).
Lotion left behind: residue keeps processing; remove each step completely.
Heat and humidity: speed up processing (Elleebana, Lashbase); watch more closely on warm days or in a warm treatment room.
Recent chemical treatments: may mean adjusted timings.

Under-processing

The opposite problem: a weak curl, or lashes that drop back to their natural position within days (Elleebana). Common causes are too little time, a shortened setting step, excess adhesive stopping the lotion penetrating, make-up or oil residue, or poorly stored product: Lashbase warns that lotion starts to degrade every time it’s exposed to air and recommends storing it somewhere cool and dry.

Uneven curl

Cause	How to avoid it
Lashes crossed, twisted or clumped on the shield	Comb them straight, parallel and separated before the lotion.
Gap between shield and lash line	Place it as close to the root as possible (Lashbase).
Shield placed too low	Causes an “L” curl; reposition before you start.
Wrong shield size	Check the size by combing the lashes onto it.
Uneven lotion application	A thin, even layer over the same zone across the whole shield.
Lashes coming away from the shield mid-treatment	Enough adhesive, and lashes completely dry before placing them (Elleebana).

Brittle or damaged lashes

Lashbase lists these signs of damage: excessive dryness, brittleness, lashes snapping or breaking, frizzing or crimping, very curly or kinked ends, uneven texture, and lashes that look weakened or thinner than usual. With any of them, don’t lift again: Lashbase is clear that visibly damaged lashes should not be treated.

Brows

Frizzy or dry hairs: processing too long, or cling film used without the manufacturer’s say-so or on damaged hair (Lashbase advises against it there).
Shape that doesn’t hold: a shortened setting step, or the client getting her brows wet or touching them within 24 hours.
Colour too dark: standard tint timing on freshly laminated hair.

Can a lash lift be corrected?

Sources are cautious and don’t fully agree. Lashbase says a correction may be possible if the lashes are healthy and the result was under-processed, depending on the manufacturer’s guidance and your training; but if the lashes are dry, brittle, frizzy, over-curled or damaged, don’t lift again. InLei’s blog describes redoing a lift with its own products using a larger shield and cutting each exposure time by 30–40%. That is one brand’s guidance for its own products: don’t apply it to other systems, and don’t attempt corrections without specific training.

Common mistakes

Giving aftercare verbally only: hand it over in writing, based on the manufacturer’s instructions.
Repeating a lift because the client “wants more curl” without assessing the lashes.
Blaming a poor result on timing alone: also check the shield, adhesive, cleansing, product storage and aftercare.
Not recording what you did (shield, timings, products): without it you can’t adjust at the next appointment.
Promising a fixed duration: it depends on each client’s growth cycle and aftercare.

Module summary

Aftercare for the first 24–48 hours varies by brand: give clients the instructions for the product you used, in writing.
Brows: 24 hours dry and untouched, then brush into place daily while damp.
The effect fades with the natural hair cycle; for lash lifts, Lashbase recommends around 6–8 weeks before repeating.
Over-processing: excessive curl, bent tips, straw-like texture, breakage. Under-processing: the curl drops within days.
Damaged lashes or brows are not re-treated.

Self-assessment

1. A client comes back a week after her lift wanting it redone for more curl. What do you do?

Don’t do another full lift. Lashbase says not to repeat one a week after the original and to wait around 6–8 weeks; the condition of the lashes must also be assessed.

2. Name three signs of over-processing.

Any three of: excessive, unnatural curl; tips curling back towards the lid; breakage; straw-like texture; thin or fragile lashes.

3. A client’s lashes drop back to their natural position within a few days. What do you look at?

Under-processing: too little time, a shortened setting step, excess adhesive, poor cleansing, badly stored product, or aftercare not followed.

4. What should the client do with her laminated brows after the first 24 hours?

Brush them into place while damp (for example after a shower) and condition them with a gel or serum between appointments.

5. Why isn’t a lash lift permanent?

It only changes the existing lashes. Through the natural cycle (a 4–10 week growth phase and a 4–11 month complete cycle, according to Aumond and Bitton) treated lashes shed and new, untreated ones grow in.
