An essential step before heat styling to lock in your style
while helping visibly improve your hair's texture.

Flexibly locks your hair in place

Transfers heat rapidly to lock your hair in place without stiffening it.

Locks curls in place (after six hours)

Smooth feel

When professional hairstylists style a section of hair with a hot iron, they gently cuddle the curl in their hands to help the heat dissipate before it loses its shape. Inspired by this technique, ReFa LOCK OIL/ReFa LOCK OIL LIGHT uses a proprietary, thermally conductive formula that transfers and dissipates heat quickly to create beautiful, soft curls and lock them into place without any stiffness.

Helps visibly repair damage

Locks in your style for longer while helping
visibly repair cuticles

Heat-protecting ingredients2 target damaged cuticles to help visibly repair them. By smoothing out cuticles and protecting the hair from humidity, dryness and other environmental stressors, ReFa LOCK OIL/ReFa LOCK OIL LIGHT extends the life of any hairstyle.

Glossy texture

High permeability helps your hair look
healthy and shiny

Enriched with 18 Phyto oils3, ReFa LOCK OIL/ReFa LOCK OIL LIGHT has hydrophilic properties that allow it to deeply permeate the hair. It gives your hair a soft, beautiful look and lets you style it just the way you like.

  • 1 The ReFa BEAUTECH CURL IRON was used at the 180℃ setting on two bundles of hair, one with a pump of the ReFa LOCK OIL applied to it and one without. The bundles were wrapped around the iron one and a half times, heated for 10 seconds, then released. They were left at a temperature of 25±1℃ and a humidity of 65±5% for six hours. Pictures were then taken of each bundle.

Choose from two textures to suit your hair and styling preferences

Flexibly locks hair in place, giving it a rich shine and wet look. We recommend this oil for tight curls and waves and full, thick-looking hairstyles.

Gently locks hair in place, giving it a natural shine. We recommend this light oil for nuanced hairstyles and for use in small sections, such as in the bangs and on baby hairs.

You can use these oils as a pre-styling treatment.

Apply an appropriate amount (3 to 4 pushes for long hair), starting at the ends and then working it in to the rest of your hair. Run your hair iron through it slowly from the roots to the end. Style it as desired.
