multiple John Frieda Defy Grey Colour Blending Shampoo (250 ml) and Defy Grey Colour Blending Conditioner (250 ml) to blend the first grey hairs in brown hair

I use both the shampoo and conditioner and they work great, blends greying hair into a darker more natural tone. You have to leave it in for the instructed time 3-5 mins, the longer the darker. It doesn't cover all the very grey / white hair around the sides completely for me, but that's good imo as It looks more natural this way, gives the hair a healthier look rather than obvious dye. It also doesn't leave any chemical smell afterwards like a dye would and does its job making the hair feel nice afterwards.

These are better than planter 39 stuff and a lot cheaper so I would definitely recommend the coverage of grey is really good.

I have been using the John Freida shampoo and conditioner for several years and I find it covers my grey enough so so there is no need to dye my hair. I ordered the duo, however was disappointed to receive an already opened flimsy envelope with only the conditioner inside. I have returned for a refund.

This product hasn’t completely covered any grey hairs - my hair has lightened over the years and isn’t all grey. However , what it has done is given my hair a better overall colour and I’m hoping after a few more uses it will hide any straggly grey ones. I’ve only used it twice. It was expensive however it will last quite a while. The conditioner does make your hair feel soft.

Pretty good, but needed to leave on for longer than stated.

Who has time to spend half a day a month at the hairdressers. Showering colour in instead can be part of your routine. A neck problem aggravated by backwashes, which I’ve since read are linked to strokes, which in turn are linked to dementia led me to need an alternative to add my natural pigment into my fading locks. It can stain a bath mat or grout if you don’t rinse off any neat product. But does the job in minutes, rather than hours.

A great product..saves so much on hair dyes and looks really good.

Been using this for a while now but sadly doesn't make a difference to my hair. Maybe my hair just doesn't take on colour very well, even when I leave the products on for longer than instructed. Smells really nice though!
