My hair usually knots up again right after I brush it, but SmoothStart made it feel softer and so much easier to comb through without weighing it down

Silky hair. A simpler routine.

See the slip. Then see the silky finish.

Shake to blend both conditioning phases.

Give your brush a smoother path.

Style it. Let it down. Feel the softness.

Your hair isn't the problem. It's missing slip.

From tangled to touchable.

You wash. You condition. Your brush still catches.

If a rich leave-in makes clean hair feel coated, more just trades one frustration for another.

Here's the better route: Surface Slip Conditioning. Smoothing conditioners coat rough strands, reducing friction for easier brushing.

Shake. Mist your lengths. Get the slip you need with a light, touchable finish.

Soft enough to stroke. Light enough to swing.

You washed your hair to feel clean.

Keep that feeling. SmoothStart softens dry lengths without a heavy cream. Your hair feels silky and still moves.

Mist damp lengths and ends. Comb through. Keep roots clear. Then let it down. Run your fingers through it.

🌿 Soft without looking greasy

💫 Exactly what my color-treated ends needed

“My highlighted ends always felt rough and tangled after washing, and heavier products just made the rest of my hair limp. I started using SmoothStart on the mid-lengths and ends while damp, and they feel much softer and easier to comb without flattening everything.” “My highlighted ends always felt rough and tangled after washing, and heavier products just made the rest of my hair... “My highlighted ends always felt rough and tangled after washing, and heavier products just made the rest of my hair limp.

🚿 Wash day is way less annoying now

“I used to spend forever trying to gently work through tangles because I was scared of snapping more hair off. Now I spray SmoothStart through my damp hair first, and brushing feels so much easier and less like a whole project.” “I used to spend forever trying to gently work through tangles because I was scared of snapping more hair off.... “I used to spend forever trying to gently work through tangles because I was scared of snapping more hair off.

Ready for easier brushing? Here's what to know.

Will it make fine hair greasy or flat?

Mist lightly onto damp lengths and ends, keep roots clear and comb through. Start with less on fine hair. Get slip without a heavy cream.

How much do I use? Wet hair or dry hair?

Lightly mist towel-dried lengths and ends. Shake first, then comb through. Adjust for length and thickness. Aim for an easy brush-through, not a soaking.

Do I still use my rinse-out conditioner?

Yes. Wash and condition, then apply SmoothStart to towel-dried hair for slip and softness before styling. Leave it in—no extra rinse.

What about color-treated hair or curls?

Soften rough, color-treated lengths for easier combing. For curls, distribute through damp hair before styling products. Coarse hair can pair it with richer conditioning.

Is it silicone-free or fragrance-free?

It contains smoothing silicones for glide and softness, plus fragrance. For ingredient allergies or fragrance sensitivity, check the bottle's ingredient list before use.

Where does it fit in my styling routine?

After conditioning, before styling. Shake, mist towel-dried lengths and gently comb through. Leave it in for soft, manageable hair. Air-dry or style as usual.
