Why Flea and Tick Pour-on Products Need Sebum
Most pour-on tick and flea products are alcohol based. This alcohol mixes with the sebum of the skin and hair and disperses over the body. When the alcohol evaporates, it leaves medication around the body. The manufacturers recommend not using the product 2 days before or 2 days after bathing. What do you think the efficiency would be if you stripped all the sebum off with a harsh shampoo or bathed without a good conditioner?
How Pour-On and Spot-On Flea Treatments Spread
Many topical flea and tick products are applied to one spot, usually between the shoulder blades. The product then spreads across the body through the natural oils on the skin and hair. If those oils are missing, the product has nothing to travel on, and coverage can suffer.
Bathing and Topical Flea Treatment Timing
- Follow the instructions on your specific product. Many manufacturers recommend not bathing for about 2 days before or 2 days after application.
- Avoid harsh shampoos that strip the sebum layer before treatment.
- Always condition after bathing so the skin has a healthy oil layer.
- Let the coat dry completely before applying a topical product.
- Ask your veterinarian about bathing frequency with your pet’s specific flea and tick product.
Why Conditioner Matters With Flea Products
A stripped coat leaves the topical product without its delivery system. Gentle cleansing followed by a hydrating conditioner helps keep the sebum layer intact. Learn more in why replace the sebum layer.
