Smooth'n glow hair serum, for frizzy hair seeking silky smoothness

For frizz control and instant shine on styled hair

A fine, clear layer settles over the surface and reflects light evenly down the length. Biodynamic Damask rose and upcycled apple seed oil smooth the strand underneath before it is sealed.

with Biodynamic Damask Rose

smooth'n glow hair serum

$75.00 - 1.7 fl oz (50 mL)

An anti-frizz leave-in serum for lengths that look dull and lift in humid air, that closes the surface of the strand and leaves a clear shine along it. Biodynamic Damask rose is naturally astringent, drawing the roughened surface back down flat, while upcycled apple seed oil seals it against damp air. A few drops finish a whole head without ever settling into weight.
Step 3 of the Smooth'n Glow routine. On damp hair before styling, or on dry hair to finish.

✽ Instant Shine: For hair that looks flat even in good condition, a fine clear layer settles over the surface and reflects light evenly down its length
✽ Holds Against Humidity: For lengths that lift the moment the air turns damp, upcycled apple seed oil seals the strand so there is nothing to lift
✽ Weightless Finish: For fine hair that drops under most products, a few drops finish a whole head and the lengths keep their movement
✽ Softens Worn Ends: Sea buckthorn carries a fat that skin itself produces, so it settles into dry ends rather than sitting on top
✽ Damp Or Dry: Works into wet hair before styling or over finished hair at the end, without changing how it behaves

I like all of the products I use from this line. My hair is healthy. Highly recommend!

★★★★★ Wendy MVerified buyer

Love this stuff! Makes my curly, frizzy hair manageable and glossy, plus the smell is heaven!

★★★☆☆ AnonymousVerified buyer

Hasn’t provided enough moisture on wet styled hair. I find myself using a lot of product. I’m going to try it again when I wear my hair straight, may provide a different result then.

The ritual.

Dispense 1–2 drops into the palm (more for longer or coarser hair), rub hands together to distribute, and run evenly through damp or dry mid-lengths and ends. Avoid the roots. Proceed with your preferred styling routine — blow-dry, air-dry, or apply as a final touch on already-styled hair for instant shine and frizz control. Reapply a single drop between washes if ends feel rough or the style needs refreshing.
