Lavender Allergy - It's a thing
Originally posted 11/17/22 Revised 3/10/25
This is a heads-up post to alert pet groomers, pet owners, and aromatherapy folks that the essential oil of Lavender, Lavandula angustifolia, AKA, Lavendula officinalis, has been identified as an allergen and an increased risk of allergic contact dermatitis. The word from the European Union is that Lavender and several other essential oils appears on the 2023 update of the official EU List of Fragrance Allergens. (See Attachment Below).
The Current list of 25 fragrance ingredients are fragrance chemicals (components of fragrances) that must be declared on cosmetic labels in the EU when their concentration in a product exceeds:
0.001% in leave-on products.
0.01% in rinse-off products.
Note that this EU regulation applies to labeling, not to formulating or usage.
What is an allergen? Also known as a "sensitizer", an allergen is a substance that has the potential to trigger the immune system to marshal an allergic response. An allergen will not trigger reactions in all individuals and it may take many exposures for an allergic response to fully develop. In the case of essential oils, sensitizing substances are the natural chemical components that make up essential oils. Each essential oil has many chemical components in varying amounts depending on the plant source. Lavender oil has 8-12 chemical substances, depending on the type and variety of the plant.
One of the components of Lavender oil, Linalool, appeared on the original EU list. A second component, Linalyl Acetate, has subsequently been identified as causing allergic reactions and now appears on the 2023 amended list (along with many others). Linalyl Acetate and Linalool, are the two largest chemical components of Lavender essential oil, accounting for 50-80% of the common varieties. (Source: Tisserand & Young, Essential Oil Safety.)
A fundamental fact to know is that lavender allergy is most often a delayed-type hypersensitivity. This means that the reaction is not immediate and can take one or two days to show up. It is more likely to happen after increased use and exposure to the linalool and linalyl acetate of lavender. (per Healthline).
Why now? Essential oils have been around forever. Why are we just recently seeing their components identified as allergens? Good question! It has to do with the huge surge in the use of Lavender and other EOs and their components in the personal care, cosmetics, and pet care industries. It takes wide use and exposure over time in order for these fragrance components to emerge as allergens. BTW, synthetic fragrances utilize the chemical components to recreate the smell of the EO or to combine it with other components to make a complex synthetic fragrance.
What does Lavender allergy mean for pet groomers? Okay, just because this allergic reaction is possible does not mean that it is likely. Lavender allergy is relatively rare. The likelihood of it happening increases with:
Concentration - full strength in direct contact with skin raises a much greater risk than highly diluted in a spray product for the coat. Some of the most prevalent cases of Lavender allergy have been connected to use in massage therapy.
Duration of contact - Brief contact in a rinse-off shampoo is much less likely to spark a reaction than contact in a cream that is left on the skin.
Frequency of contact - Lavender allergy has been identified as an occupational hazard. The massage therapist using Lavender in a massage oil several times a day is at greater risk than a person getting a massage with lavender fragrance once in a while.
Sensitivity of the individual - individuals (dogs or humans) who have experienced allergic reactions to other things are more likely to have a reaction to fragrance chemicals. There are people and dogs who have an overactive immune system.
Conclusion: We do not need to ditch our fragrances or essential oils now that we know about fragrance allergy reactions. We need to be mindful that delayed reactions can occur and not be in denial. The fact that a pet leaves our care not showing any signs of itching, rash, hives, etc. does not guarantee that there is not a problem related to our products. And be aware that bathing staff is at the greatest risk of fragrance allergies, especially if they are using the same product repeatedly. The old notion that lavender was a completely benign and harmless “natural” alternative is simply not true. Now you know! Listed below is the complete list of essential oils contained in the draft of the soon-to-be-added fragrance allergens. (2023)

TECHNIQUES OF DEMATTING
Matting is the bane of the groomer’s life, whether professional or pet parent. Mats spoil the fun of styling, and dematting is sometimes uncomfortable or even painful for the pet. Matting occurs when knots and tangles bunch together and accumulate. A few hairs in a knot can be called a “tangle”; something the size of your finger, a golf ball or greater is a “mat”. There is often more than just one, and some coats have a tendency to “felt” or mat tightly against the skin. Groomers of rescued pets often see completely felted coats that come off in huge pieces.
Dematting skill is something that is developed with practice over time,
much like scissoring and styling. The following techniques are offered as a means of developing your skill in dematting. The more you utilize these techniques, the greater speed you will develop at achieving your result, with the least possible discomfort to the pet.
DIVIDE AND CONQUER - MAT SPLITTING
Splitting matted fur into smaller pieces is your fundamental key to success. By slicing your matted area lengthwise into smaller pieces, you have a much better chance of untangling the hair. There is also less discomfort to the animal to have small pieces of hair worked on rather than a large mass. One of the best tools for splitting mats is a plastic letter opener style that looks like a business card, with a single “tooth” and a blade in the corner.
Mat splitting requires care and paying attention. Because you need to use a very sharp tool, there is always danger of slicing something besides hair. Watch out for edges of ears, folds of skin, and the tips of tails. Scissors can be used with great caution, ALWAYS working away from the skin. Never cut into mats with scissors pointing inwards to the dog.
Another way of dividing and conquering matting is to shorten the matted coat first. Using your "rough out" shears (an older, less valuable shears) roughly scissor off some of the length. This is especially effective on poodle or poodle mix coats. Oftentimes scissored off mats will brush apart after bathing on these coats. Just try it!
PICK DON'T PULL
Most matted hair will break apart more easily if you use a picking action, rather than trying to pull a comb or rake through a hunk of hair. Correct picking technique is very similar to the technique we use to comb up hair in preparation for scissoring. You are lifting the tool in and out of the hair, not pulling through. Pick from the ends of the hair toward the skin, not from the skin out. Relax your wrist and get a sort of whipping action going. The objective of picking is to loosen the hair. Later you will get more separation with a comb.
FROTHING
The concept of frothing emerged in the moment during the demonstration of
dematting techniques at Atlanta Pet Fair, 2005. I was doing rapid picking action in a matted area on a Cocker Spaniel, using a Mat Breaker tool. As the undone fur rose to the surface, it formed sort of a foam on the top of the coat. "Look!" I exclaimed, "It's FROTHING!" Voila! A concept was born.
Frothing is helpful when you are working on a larger matted area and it is an alternative to picking each little piece apart. Lightly whip in a wider area and then brush out the froth and continue with the comb. Or more frothing...
ATTACK FROM THE SIDE
Once you have an area divided by splitting and loosened by picking, you can finish by combing through. I recommend using a coarse comb and working from one side of an area of matted hair rather than a front and center approach. If possible, hold a piece of hair in one hand and comb with the other. Holding the hair with your fingers between the part being combed and the skin will reduce discomfort to the animal. Release your hold to get the last bit of combing to the skin.
BLOW IT OUT - THE USE OF AIR
Air flow can be used as an aid in untangling hair, either from a high velocity dryer or a traditional stand/arm dryer. The action of the air serves to shake loose some of the hair that is woven together in a tangle. In the case of more coarsely textured hair, much detangling can be done with air flow and splitting of larger areas. On finer coats, the use of air flow from an arm dryer while fluff drying will speed up dematting.
BATHING - THE USE OF WATER
Many groomers were trained with the admonition to never bathe a matted coat. It was cautioned that bathing would cause the matted fur to tighten its grip. This is true if the matted fur is not combed out after the coat is dried. Cleaning and conditioning a matted coat can often help to release the grip of tangles, and some products, such as the silicones mentioned above actually work best when dried into the coat.
Avoid rubbing products into tangled hair, as rubbing can worsen the situation. Squeeze products through the coat and pat dry with towels. On a heavily matted coat, It is recommended that you do some mat splitting before the bath, thus insuring that your bathing will be thorough, products will be distributed, and hair thoroughly saturated. Big clumps can be difficult to penetrate.
TOOLS AND PRODUCTS
Find the tools and products that work best for you. For the purpose of
splitting large matted areas, look for tools that have replacement blades. These tools are only as effective as they are sharp. I use a letter opener splitter from www.groomersmall.com. Another of my favorite dematting tools for large matted areas is the Mat Breaker. It has small, curved blades.
Find out if you prefer the rake style or comb style mat tool.
Look for a wide tooth comb or coarse comb. The Chris Christensen extra coarse-fine comb is great on small dogs such as Bichon, and Shih Tzu. A larger wooden-handled poodle comb is good for larger dogs, such as the Doodles.
Some brushes can be helpful. The Mars Flexy King brush is excellent for breaking up small mats. This imported brush is becoming hard to find. It is at www.groomersmall.com. Extra firm pin brushes are helpful. We’ve used the Chris Christensen 16mm T Brush for years. The Les Pooch “Emergency” brush is extra firm and works for large matted areas.
A pair of blending shears is also helpful for dematting. Blenders have one notched tooth blade and one straight blade. They can be used to break up mats or to cut out stubborn knots with less danger of slicing the dog or leaving a huge hole in the coat.
SLIPPING N' SLIDING
Products which make the hair slippery will ease the detangling efforts.
There are plenty of different products to try. One of the most slippery
products is Cowboy Magic Detangler and Shine. Another silicone gel is
Eqyss Survivor. Remoisturizers and thick conditioners work well if used full
strength directly on the mat. One of my favorites is Chris Christensen Spectrum 10 HyproPac. Less bad mats can be teased apart with aid from diluted spray-in conditioners. Some groomers do much of their dematting in the tub on a wet
pet.
On a dry coat, grooming powders and even corn starch can lubricate the hair shaft for increased ease in tangle removing. Wear a face mask if you choose this
route, so you don’t inhale a lot of powder as you work.
Grooming products with a silicone base, such as Chris Christensen Ice on Ice, The Stuff, Quicker Slicker, AbraCaDaBra and Best Shot coat each hair shaft with slick silicones. Silicone sprays work best when dried on to the coat. It requires a leap of faith to trust that dematting will easier after the coat is bathed and dried. I have also used hair serum products from the human hair aisle that are marketed as “anti-frizz” or “hair glossing”. A good one from Sally Beauty is Fantasia Frizz Buster Serum.
