Professional demi-permanent color

L'Oréal Dia Color 4.15/4BRv is a demi-permanent alkaline gloss formulated without ammonia. It is intended for professional colourists working on natural or previously coloured hair. The shade delivers rich, deep reflects with visible shine even on darker bases. It covers up to 70% of grey hair when applied at the same level as the original colour.

57 g tube covers partial grey

The 57 g tube provides enough product for a standard single application on short to medium length hair. It comfortably handles up to 70% grey coverage on a like-for-like depth. Coverage diminishes on resistant white hair or when a lighter target shade is chosen. A second tube is needed for long, thick hair or full-head retouch work.

Ionene G and Incell complex inside

The formula includes an Ionene G and Incell technology complex designed to strengthen and protect the hair fibre during the colouring process. This conditioning system helps maintain hair integrity and boosts shine after rinsing. No separate developer or after-care sachets are bundled with the tube. The product requires professional expertise for correct mixing and timing.

Questions about this item

Will the 1.7 oz Dia Color 4.15/4BRv work over previously coloured hair without lifting the base?

Yes, it is a demi-permanent alkaline formula without ammonia designed to deposit rich, deep reflects on natural or coloured hair at the same level as the original shade.

How can I confirm the Ionene G + Incell complex is protecting the fibre during processing?

You will notice the hair feels stronger and looks shinier immediately after rinsing, with visible shine even on a dark base.

Does the 57 g tube include the developer or must I buy it separately?

The tube contains only the colour cream; a compatible alkaline developer must be purchased separately for mixing.
