**The answer is a cuticle-coating conditioner. These formulas sit on top of the hair shaft and build up fast on fine strands, weighing them down.**

The fix is matching product weight to hair texture — fine hair generally does better with a light leave-in, while heavier cuticle-coating formulas are better saved for coarse or damaged hair that needs the extra coating. Using a heavy conditioner on fine hair is one of the most common reasons a client's hair looks oily by afternoon even though they washed it that morning.
