Pravana Locked-In colours come in a thick gel-like consistency which helps prevent them from bleeding into each other. Using the Locked-In line, you can put colours that would usually bleed, such as red or purple, next to yellow without fear of the yellow being polluted by the other colours.

Hair Dyeing Fun with Pravana Locked-In

You can see how the colours don’t run. They’re intermixable, so you can create your own shade using colour mixing rules.

All Locked-In colours have a wonderful translucent quality so you can layer up the colour to create interesting effects like we did in the article above.

Have fun and be creative!


For the most vibrant results, apply directly to pre-lightened dry or slightly damp hair (pale blonde is best). It’s best to shampoo with a clarifying shampoo but avoid using conditioner before application.

Wear protective gloves and avoid getting colour on skin as staining may occur. To achieve an even coverage we recommend applying the product using a tint brush. More than one tube will be required for medium-long or very thick hair. It’s always better to have plenty of dye available but if you buy too much you’re welcome to return any unused product for a refund (please see our returns policy for details).

Do not mix with developer. Allow the product to soak into your hair for at least 15 minutes (most people wait at least 30 minutes) before rinsing with warm water. Please remember to carry out a strand and sensitivity test before use.

Reviews of Pravana Locked-In Blue

  • This was an excellent color and it lasted quite awhile in my hair. I had a mix of locked in blue, locked in teal, and locked in purple. The blue stayed true for a very long time, the teal stayed true for about two months. The purple... vanished in less than a week without a single wash. It was layered back over with just the teal and it stayed great for two months before starting to go green. Refreshing it with more of the same teal color did not seem to help bring back that brightness, but it did go blue for a bit. Overall, great color but it does have a green undertone.
  • This only took to the very lightest bleached parts of my hair, but it did last. If you want blue coverage all over, try the Adore Indigo Blue. The Adore brand even took to my natural dark brown hair as well as the yellow bleached parts.
