Anyone with blonde, lightened, highlighted or chemically treated hair that feels dry, fragile or damaged. Oligo states the shampoo suits all hair types and colours, so it also works on non-blonde hair that has been weakened by colour or heat.

It is a retail product for everyday home use, sold in a 300 ml bottle and a 946 ml pump size that salons and frequent users often prefer.

Bleaching and lifting strip the lipids and proteins that keep blonde hair strong, and a standard shampoo does nothing to replace them. This one cleanses gently while depositing a ceramide, plant proteins from quinoa, chickpea and lentil, and a blend of apricot kernel and argan oils, so each wash is also a small repair step. It is designed as the base of the Blacklight REP routine, so it pairs naturally with the Repair Conditioner, Leave-In and Mask when hair needs ongoing strengthening rather than toning.

• Apply to wet hair.
• Lather and massage into the scalp and lengths.
• Rinse thoroughly.
• Follow with Blacklight Repair Conditioner or Repair Mask for best results.

Pros:

• Mild cleansing base that suits frequent washing of lightened, fragile hair
• Ceramide plus quinoa, chickpea and lentil extracts aimed at rebuilding strength and elasticity
• Contains no blue or violet toning pigment, so it will not shift the shade of your blonde
• Large 946 ml pump size available

Cons:

• Does not neutralize brassiness; blondes fighting yellow or orange tones need a toning shampoo alongside it
• Low-lather sulfate-free formulas can feel less foamy than conventional shampoos
• Fragranced, so less suited to anyone avoiding fragrance
