(Coat Health Part 2)
Why do different coats need different shampoos? 🛁
A shampoo isn’t just a cleanser — depending on its formulation, it can add moisture, add volume, make a coat heavier and silkier, repair structural damage, support skin health, or deep clean right down into the follicle. Using the wrong one for your dog’s coat type can actively work against the finish you’re looking for.
Here’s how some of the key types differ:
Moisturising shampoos are formulated with ingredients like colloidal oatmeal, aloe vera, glycerin, and coconut oil. Vitamin B — commonly found in oats — pe*****tes deeply to deliver moisture, while vitamin E nourishes the skin and helps detangle the coat. These are ideal for dry, brittle, or damaged coats — or breeds prone to skin sensitivity. They add softness and suppleness without weight.
Volumising shampoos work differently — they coat the hair shaft lightly to lift and separate, giving the coat more body and texture. Dogs with wire coats, such as terriers, need volumising shampoos particularly to assist with hand stripping, as a coat that has been softened is far harder to strip correctly. Using a moisturising shampoo on a wire coat actually works against the coat’s natural structure.
Strengthening and repairing shampoos often contain keratin — the same protein that makes up hair, skin, and nails — which works to smooth the hair shaft, reduce frizz, and repair structural damage to the coat, making it stronger and less prone to breakage over time. Keratin however is only effective when high heat is used to help bond it to the hair shaft.
Deshedding shampoos are formulated to pe*****te the undercoat and loosen dead hair during the bath, making it far easier to remove. These formulas support a healthier coat and help keep excess fur manageable — using omega-rich plant oils, aloe, and oatmeal to moisturise the skin while supporting the coat’s natural shedding cycle.
Whitening and brightening shampoos use optical enhancers and proteins to bring out natural coat colour — particularly useful for white or light-coloured coats that can yellow or dull over time. Often these are blue in colour, just like the blue shampoos you can buy for blonde hair humans, the blue particles sit in the hair shaft and dilute the yellow tones of the hair.
Medicated and yeast-support shampoos go deeper still — targeting specific skin conditions with active ingredients like Piroctone Olamine, which works to reduce yeast and dandruff while essential oils like peppermint, eucalyptus, and rosemary provide a gentle, therapeutic cleanse.
What this means in the salon:
At The Dog Retreat Spa we don’t use the same shampoo on every dog. A cocker spaniel with oily, yeast-prone skin gets something completely different to a doodle with a dry, brittle coat, or a double-coated breed coming in for a de-shed. The shampoo selection is a decision — not a habit — and it’s one of the things that separates a thoughtful groom from a conveyor belt one.
If you’ve ever wondered why your dog’s coat looks and feels noticeably different after a professional groom than after a bath at home, this is a big part of the answer. 🐾✂️
