Lash Lift and Brow Lamination Course: Introduction

Course: Lash lift and brow lamination course from A to Z · Module 1 of 8

Welcome to Lash Canarias’ free online lash lift and brow lamination course. In this first module you’ll learn what each treatment actually is, how a lash lift differs from lash extensions and from a traditional lash perm, what European cosmetics law says about the products involved, and what this course can and can’t do for you.

Before you start: this course is for education and information only. It is not a substitute for hands-on, in-person training with a qualified trainer, it does not lead to a certificate or qualification, and it does not on its own prepare you to treat clients. Always follow the manufacturer’s instructions for each product – timings, amounts and steps vary from brand to brand.

Module objectives

Define precisely what a lash lift and a brow lamination are.
Tell a lash lift apart from lash extensions and a traditional rod perm.
Understand why results are temporary and what determines how long they last.
Know the basics of the EU cosmetics rules that apply to these products.
Get an overview of the rest of the course.

What is a lash lift?

A lash lift is a chemical treatment that reshapes the client’s own lashes, lifting them from the root. The lashes are combed onto a silicone shield (also called a pad) attached to the eyelid, and two lotions are applied: the first softens the internal structure of the hair so it takes on the shape of the shield, and the second sets that new shape. Many systems add a third, conditioning step. We’ll look at the chemistry in detail in Module 2.

It’s worth being clear from day one about what a lift does not do. As ophthalmologist Nicole Bajic explains for Cleveland Clinic, a lash lift curls existing lashes so they look longer and fuller, but it doesn’t actually lengthen or thicken them. The “longer” look comes from lashes that used to point forwards or downwards now being seen standing upright.

How long does it last, and why?

Results are semi-permanent: they last until the treated lashes shed and are replaced by new, straight ones. Sources give slightly different figures, so the honest answer is a range rather than a single number:

The California Board of Barbering and Cosmetology says approximately 4 to 6 weeks, following the natural growth cycle.
Healthline gives around six weeks on average.
An eye clinic (ReFocus Eye Health) and the manufacturer InLei both mention up to 6–8 weeks.

The reason lies in lash biology. According to a review by Aumond and Bitton in the Journal of Optometry (2018), the growth (anagen) phase of an eyelash lasts four to ten weeks, the full life cycle four to eleven months, and a lash grows 0.12–0.14 mm a day. Because each eye has lashes at different stages, the curl fades gradually as lashes are replaced rather than disappearing all at once.

As for appointment time, Cleveland Clinic and Healthline both put a full lash lift at about 45 minutes, although this depends on the system and on whether a tint is added.

What is brow lamination?

Brow lamination applies the same chemical principle to the brow hairs. One lotion loosens the bonds inside the hair, the hairs are brushed into the chosen direction (usually up and slightly outwards), and a second lotion sets them there. The result is a fuller-looking, groomed, more uniform brow – no needles, no pigment.

The California Board groups both services together as “lash and brow perming” and notes they’re commonly known as lash lifts and brow lamination. According to Medical News Today, lamination typically lasts 6 to 8 weeks and a full appointment takes around 45–60 minutes; it’s often paired with shaping and tinting, which we cover in Modules 6 and 7.

One crucial point: although the chemistry is similar, the products are not interchangeable. In brow lamination the lotion sits on the skin of the brow, whereas a lash lift is carried out right next to the eye. InLei, for instance, states that its Brow Bomber brow system must never be used on lashes, as it can cause serious eye damage.

Lash lift vs lash perm vs extensions

Clients often ask for “something to make my lashes look better” without knowing which option suits them. Here are the key technical differences:

	Lash lift	Traditional lash perm	Lash extensions
What’s done	Natural lashes are reshaped with chemical lotions	Natural lashes are curled with chemical lotions	A synthetic fibre is bonded to each natural lash
Shaping tool	Flat silicone shield	Cylindrical rod	Tweezers and adhesive
Where the lotion goes	Roughly the first third of the lash, from the root	Usually the full length	No perm lotion; adhesive is used
Typical result	Lift from the root	Tighter curl (C or D shape)	Adds length, curl and volume
Upkeep	Repeated as new lashes grow in	Repeated as new lashes grow in	Regular infills

The lift-versus-perm comparison draws on Divine Lashes’ guide and on Beautiful Brows & Lashes’ explanation of shields and rods: a shield gives a direct lift at the root, while a rod mainly produces curl. Some salons use “lash perm” to mean a lift, so always ask which technique was used when a client tells you about past treatments.

Where do extensions fit in?

Extensions are a completely different service: synthetic fibres attached to natural lashes with an adhesive. The US FDA treats lash extensions and their adhesives as cosmetics, and a review in Medical Hypothesis, Discovery and Innovation in Ophthalmology (Masud et al., 2019) notes that these glues are primarily cyanoacrylate-based. If that’s your interest, see our lash extension course and the lash extension supplies category.

From the client’s point of view, a lift usually appeals to people with reasonable lash length whose lashes are straight or point downwards and who want a natural result; extensions appeal to those wanting more length or density than they have. The final call belongs in the consultation (Module 4), once you’ve assessed the lashes and the eye area.

What EU law says

Lash lift products are cosmetics and in the EU they fall under Regulation (EC) No 1223/2009. Annex III of that regulation restricts thioglycolic acid and its salts, the most common active in lash lift lotions. Since Commission Regulation (EU) 2015/1190, the specific entry for eyelash waving products sets out:

A maximum concentration of 11% (calculated as thioglycolic acid), with a ready-for-use pH of 7 to 9.5.
Professional use only.
Conditions of use: avoid contact with eyes, rinse eyes immediately if the product gets into them, and wear suitable gloves.
Mandatory label warnings: “For professional use only”, “Contains thioglycolate” and “Follow the instructions”.

Why professional only? In 2013 the EU’s Scientific Committee on Consumer Safety (SCCS) concluded that home use on eyelashes isn’t recommended because of the potential for eye irritation, but that concentrations up to 11% are safe when applied by a professional, since that reduces the risk of direct contact with the eye. The SCCS also stressed that the safety of these products depends heavily on responsible risk management, including warnings and detailed instructions. (If you work outside the EU, check your own country’s rules.)

Another key point: the California Board warns never to use hair perm solution on lashes or brows, as it can cause blindness and damage to the eye area. Only ever use products formulated specifically for lashes or for brows, such as those in our lamination and lash lift category.

How to get the most from the course

Work through the modules in order. Technique (Modules 5 and 7) only makes sense once you understand the chemistry and the safety side.
Keep your system’s instructions to hand. Whenever the course says “according to the manufacturer”, check the leaflet for the kit you’ll actually be using.
Do the self-assessments. Each module ends with questions and answers so you can check your understanding.
Practise under supervision. Find in-person training with a qualified trainer before working on real clients.
Talk to your insurer. The California Board encourages practitioners to check their liability insurer’s requirements for these services – sound advice wherever you work.

Common mistakes

Promising that a lift makes lashes longer. It changes direction and curl; length stays the same.
Promising an exact number of weeks. It depends on each person’s growth cycle, so talk in ranges.
Using hair or brow products on lashes. They’re formulated for other areas and can harm the eye.
Mixing up a lift and a rod perm. They give different results; ask what was done before.
Assuming an online course is enough. Theory is the foundation, but technique is learned through supervised practice.

Module summary

A lash lift reshapes natural lashes from the root over a silicone shield; brow lamination applies the same principle to brows.
Results are temporary – sources range from 4 to 8 weeks, depending on the growth cycle.
A traditional perm uses rods and gives a tighter curl; extensions add fibres with adhesive.
In the EU, thioglycolate-based eyelash waving products are professional-use only, capped at 11% with a pH of 7–9.5.
Lash, brow and hair products are not interchangeable.

Self-assessment

1. Does a lash lift make lashes grow longer?

No. It changes their curl and direction so they look longer, but it doesn’t increase their length or thickness.

2. Why does a lash lift fade over the weeks?

Because treated lashes complete their cycle and shed, and new lashes grow in without the curl. The literature puts the eyelash growth phase at four to ten weeks.

3. Which tool distinguishes a lash lift from a traditional perm?

A lift uses flat silicone shields that lift from the root; a traditional perm winds the lash around cylindrical rods, giving a tighter curl.

4. What restrictions does EU law place on thioglycolate lash lift lotions?

Professional use only, a maximum of 11% calculated as thioglycolic acid, pH 7–9.5, gloves, avoiding eye contact and mandatory label warnings.
