Learn how to use Restore Repair Leave-In on damp or dry hair to prevent split ends and strengthen damaged strands without weighing them down.

Quick answer

Apply Restore Repair Leave-In to clean, damp hair after washing, focusing on mid-lengths and ends. Use a small amount—start with a pea-sized drop and add more only if needed. For dry hair touch-ups, smooth a tiny amount over ends to tame frizz and add moisture without re-wetting.

Why damaged hair needs a leave-in (and when to skip it)

Damaged hair has a rougher cuticle that loses moisture quickly and splits easily. A leave-in conditioner like Restore Repair Leave-In helps seal the cuticle, provide slip for detangling, and deliver lasting hydration. It also offers heat protection and can prevent up to 93% of split ends caused by styling, according to the brand. Skip it only if your hair is extremely fine and easily weighed down—in that case, use a tiny amount on ends only or every other wash.

Damp vs. dry: which application is right for you?

Damp application is best for overall repair and protection: hair absorbs the product more evenly and you can distribute it from mid-lengths to ends. Dry application works for quick fixes—smoothing flyaways, refreshing ends, or adding shine between washes. Avoid applying to soaking wet hair, which dilutes the product and can make it runny; towel-dry first. On dry hair, use less than you think—a little goes a long way.

How much to use (and how to adjust for your hair type)

Start with a pea-sized amount for fine hair, a nickel-sized amount for medium hair, and a quarter-sized amount for thick or coarse hair. Rub the product between palms to warm it, then rake through mid-lengths and ends with fingers or a wide-tooth comb. If hair feels sticky or looks stringy, you used too much—rinse or skip the next application. For very damaged ends, you can layer a second small amount just on the tips.

Step-by-step application

Start with clean, damp hair: After shampooing and conditioning, gently towel-dry hair until it's damp, not dripping. If you're applying on dry hair for a touch-up, skip to step 4. Checkpoint: hair should feel cool and slightly damp, not wet.
Dispense the right amount: Start with a pea-sized amount for fine hair, a nickel-sized for medium, or a quarter-sized for thick hair. It's easier to add more than to remove excess. Mistake to avoid: using a large dollop all at once—this can leave hair greasy.
Distribute evenly from mid-lengths to ends: Rub product between palms, then rake through hair with fingers or a wide-tooth comb. Focus on the oldest, most damaged parts—usually the last 2–3 inches. Avoid the scalp unless your hair is very dry. Checkpoint: hair should feel coated but not sticky; if sticky, you've used too much.
Style as usual or air-dry: No need to rinse. Proceed with blow-drying, heat styling, or air-drying. The leave-in helps protect against styling damage and makes hair easier to comb. Mistake to avoid: applying after heat styling—apply before to get the protective benefit.
For dry hair touch-ups, use sparingly: Warm a tiny drop (half a pea) between palms and smooth over ends or frizzy areas. Don't reapply to the same section repeatedly. Checkpoint: if hair looks piece-y, you've over-applied; use less next time.
