Who it's for

Curls, coils, and waves that drink up moisture and still feel thirsty. Reach for the mask if your hair feels dry, rough, or straw-like after washing — or if heat, color, braids, and protective styles have left your strands parched and craving softness. Fine to thick, 3a curls to 4c coils. If your crown is asking for a deep drink, this is the answer.

How it works

1. Cleanse first. Start on freshly washed, damp hair so every strand is open and ready to absorb.
2. Soak it in. Work a generous amount from root to tip, concentrating on the ends. Let it sit 5–15 minutes — add heat or a cap to go deeper.
3. Rinse and feel it. Rinse with cool water to seal. Hair comes out softer, more defined, and easier to manage, with that fresh-wash-day glow.

This is Step 3 of the Sierra Starr ritual — use it after cleansing and conditioning, or on its own once a week whenever your hair needs a reset.

Not sure which to choose?

Just the mask, the mask with oil to seal, or the whole wash day — every step works together.
