Details.
Professional colourists recommend options from leading brands. Temporary colouring lasts approximately 1 to 2 months and provides a natural-looking shade. Semi-permanent colouring lasts approximately 2 months, contains a mild oxidising agent, slightly lightens hair without ammonia, and partially covers grey hair. Permanent colouring provides durable colour and can lighten or darken hair. Gloss adds shine to coloured or uncoloured hair without ammonia.
