With therapeutic shampoo, there are several levels of concentrations we can create.  This again is the beauty in some of the DIY Therapeutic Shampoos - you can make it as mild or as strong as you need or desire.  If you add an entire 2mL bottle of a "neat" animalEO Essential Oil to 2oz of shampoo - you will create a 3% concentration of essential oil - which is just about perfect for almost any need.  Make sure you "tap" the bottom of the 2mL bottles to get the oil out - they don't "drip" like other sized bottles!  Read about the 2mL bottles HERE


There are a few situations in which I might make the shampoo stronger, or less concentrated - but 3% is a perfect start for almost any animal!  For other cases, such as small critters, cats, or sensitive dogs - we might add only 1mL to 2oz of shampoo.  And for a really stubborn flea or lice issue, I might add 2mL of Away to 1oz of shampoo.  In general - the rule of "start with less, and you can always add more" - will always apply.


There are many different batch sizes you can make with essential oils and shampoo.  And YES - you can use an RTU formula in your shampoo as well.  The RTU formulas, however, are already diluted in Fractionated Coconut Oil.  So this means that you may encounter a few situations by using them as an addition to your shampoo.  First, you are adding a bit of fatty oil to the shampoo.  This is really no big deal, as they mix together well - but you may change the shampoo's ability to lather or the "chemistry" of a shampoo a little bit, depending on how much you end up adding.  But, I have added RTU formulations into shampoos (and even my lotion) - and it can work out just fine.  The bigger problem with adding RTU formulations into shampoo - is that they are just much "weaker" in concentration in the final result.

Imagine a world where your shampoo is not harmful.  Imagine a world where your shampoo can actually support health, instead of contribute to toxic chemical exposure.  Imagine that world today!

We're teaming up with 4-Legger® Organic Dog Shampoo (YES! it's for other animals too!) - to combine the best of both worlds!  Non-toxic, organic and totally safe shampoo - with animalEO Essential Oil blends.  Now you can have the only ALL-NATURAL, veterinary recommended, veterinary inspired, therapeutic shampoo - that will support every part of the body - emotional and physical!

As a holistic vet, I cringe every time someone lists off all of the toxic shampoos their vet has prescribed their precious pet.  Filled with synthetic, toxic chemicals - it is no wonder why dogs have "chronic" skin issues that never resolve.  In my world, I can not only help eliminate yeast and bacterial infections from the skin - but also support the immune system to be healthier - and to keep away secondary infections in the future!  This is what essential oils add to a non-toxic shampoo base!  The ability to contribute antibacterial and antifungal actions - but to also SUPPORT the normal function of the immune system, instead of suppress it.  And, essential oils also carry anti-inflammatory, antihistamine, anti-tumoral, anti-viral, anti-microbial, and anti-insect actions as well!  What!?  A flea shampoo that not only helps eliminate fleas - but is HEALTHY for the animal???  Or even a shampoo for a senior dog - that supports comfort from achy joints or muscles?  Could it be?  Or instead of toxic chemicals that contribute to the harm of animals with seizures - a shampoo that can support nerve function and repair?  YES - it is not a fairy tale!  This is my life as a specialist in Veterinary Aromatic Medicine!  These DIY Therapeutic Shampoos will change your animals life!


6% Concentration of Essential Oil in Shampoo: used for special situations, and generally under the guidance of a vet.

Obviously - you will not be using the entire "recipe" amount to bathe your animal!  These concentrations take into account that you may shampoo twice, or that you may need more or less shampoo for certain coats, breeds, etc.  Please follow the shampoo manufacturers recommendations on how much shampoo is used, and how it is used.  Some shampoos are concentrated, and can be further diluted during the wash.  For most of our calculations - we are basing them off of adding to the 4-Legger Unscented Organic Dog Shampoo - and using according to their instructions and recommendations.  

So if you are bathing a cat (and let's just admit it, there are few situations in which regular bathing of a cat is going to be recommended) - I see no reason to not include essential oils in the event.  Say it is a 100% normal cat (they would argue...then WHY are you bathing me!) - if I am going to go through the trouble of bathing them in the first place - I might as well get my "oils on" and add KittyBoost to the shampoo!  Why not!  It is just one more beneficial layer of help that I can provide to my kitty!  So - adding 1mL of KittyBoost to 1oz of Shampoo is likely way more than enough shampoo for a cat.  Sometimes I like to make up "single shampoo" amounts.  A Tablespoon of shampoo is technically 15mL or 1/2 oz of liquid.  Let's give you a little chart of amounts and additions.

With all Therapeutic Shampoos - contact time can play an important factor in the benefits you will see.  Once your animal is lathered, allow the lather to remain for approximately 10 minutes.  Yes, this can be the longest 10 minutes of your life!  You may only get 5 minutes.  But the main point being, don't just lather up and rinse right away.  We want to allow the essential oils to contact all of the creepy crawly critters, nasty microbes, and inflammed skin cells - before you rinse it down the drain!


You can add essential oils to any other rinse or conditioner that you may be using as well - just follow the same guidelines.  For an item that may not be rinsed off after application - start with the 1.5% concentration.
