Best Shampoo for Dull Hair

The best shampoo for dull hair depends on why it looks dull in the first place. Hair shines when its outer layer, the cuticle, lies flat and smooth so light bounces off it evenly. When hair looks flat, look for the usual causes: buildup sitting on the hair, dryness that roughs up the cuticle, colour that has faded, or oil weighing it down. Each needs a different shampoo, so choose by cause, not by the word "shine" on the bottle.

Work out why your hair looks dull

• Buildup. Hair feels coated, heavy or waxy, and your styling products don't work like they used to. Common if you use dry shampoo, oils, sprays or rich creams most days.
• Dryness or damage. Hair feels rough, tangles easily and the ends look frayed. Colour, bleach and hot tools all lift the cuticle over time.
• Faded or brassy colour. The hair itself may be in good shape, but the tone has gone flat, warm or yellow.
• Oily roots. Oil drags the hair down at the root, so it looks limp rather than glossy.

Match the shampoo to the cause

For buildup, use a clarifying shampoo about once a week, then go back to your usual wash. It cleans harder than an everyday shampoo, so it's not one for daily use, especially on dry or coloured hair. Often this alone sorts out dullness, and you don't need to replace your regular shampoo at all.

For dryness, choose a moisturising or smoothing shampoo with a gentle cleanser. Sulphate-free formulas clean more softly, which suits hair that's already dry. If your hair is dry but still strong, our best shampoo for dry hair is the closer match. If it's also snapping or splitting, go to our best shampoo for dry damaged hair instead.

For faded colour, a colour-care shampoo helps slow how fast tone washes out. For grey, silver or very light blonde hair that has turned yellow, a purple or silver shampoo once or twice a week cancels out the warmth. The best shampoo for grey hair covers those.

For oily roots, a light, balancing shampoo works better than a rich one. Heavy moisturising formulas can make oily hair look even flatter. Our shampoo for greasy hair picks are made for this.

Shampoo cleans, conditioner brings the shine

The best shampoo for shiny hair sets you up by cleaning without roughing the hair up. Most of the visible shine comes from what goes on after. Conditioner smooths the cuticle back down, and that's what makes hair reflect light. If your hair is clean and healthy but still not shining, look at your conditioner before you change your shampoo.

Pair your shampoo with the best conditioner for dull hair. If your ends still look flat once dry, add a leave in conditioner for dull hair through the mid-lengths and ends.

If what you really want is soft, smooth hair that slips through your fingers, the best shampoo for silky hair leans more towards feel. Shine usually comes along with it.

Small habits that help

• Shampoo the scalp, not the lengths. The lather that runs through as you rinse is enough for the ends.
• Rinse well. Leftover shampoo or conditioner leaves a film that dulls hair.
• Finish with a cooler rinse. Stylists do this to help the cuticle sit flat.
• Don't over-wash. Every wash takes some natural oil with it, and dry hair shows dullness fastest.
