Switch to Zero Waste Natural Shampoo & Conditioner

This mint shampoo bar is scented with essential oils of mint and rosemary (good for hair growth), it contains coconut oil, vitamin E and oils of olive and grapeseed.

The chamomile conditioner bar is made with nourishing oils of jojoba, grapeseed, rapeseed & coconut, with rhassoul clay to aid detangling. Just rub between wet hands and run through hair, leave for 2 minutes then rinse well with warm water. Also in mint & lavender.
Green People’s Organic Shampoo Bars

Green People’s shampoo bars are made with organic ingredients, and due to no soap, you’re not left with sticky residue (no ‘transition period’ needed). Containing shine-boosting oils of argan and macadamia alongside frizz-fighting ingredients, one bar lasts 60 washes and most people won’t need conditioner. Also in ginger.
Most shampoos contain sodium lauryl sulphate (used to degrease engines). So imagine what it does to your scalp (some believe long-term use can prevent hair growth).
If you’ve ever used a shampoo and ended up with ‘welts on your head’, try switching to a natural shampoo for a few weeks, and you should notice a positive difference.
Green People’s Liquid Shampoos

If you prefer liquid shampoos, Green People offers nice organic vegan ones, sold in easy-to-recycle sugar-cane packaging. Everything from scent-free to repair shampoos, to combined shampoos/shower washes.
Battle Green’s Dry Shampoos (in paper packs)

Battle Green’s organic dry shampoos are made with cornstarch, arrowroot powder and kaolin clay, with aloe vera and almla fruit powder to soothe the scalp. Scented with mint & tea tree oil or orange & neroli, they are sold in a cardboard shaker pot, with refill sachets (store in a dry cool place).
As well as avoiding paying for water to be shipped to your door (the ingredient in most liquid shampoos), dry shampoos are convenient if you have no regular access to a shower, and are also good for disabled people (and their carers who find it difficult to use a shower or lean over a sink).
They are also good for people with fine hair who find they need to ‘wash hair daily’, but prefer not to actually wet and shampoo their hair each day.
Sprinkle a little dry shampoo powder directly onto the roots of your hair (or into your palm) and apply with your fingers. Work into the roots, let it sit for 30 seconds to absorb oil, then brush through to remove excess powder.
Most dry shampoos are made with volatile organic compounds, which irritate the scalp and are made with talc (a mined substance with concerns over ovarian cancer). Some even contain flammable butane flammable gas (bin empty cans or take half-full ones to toxic waste).
The ‘no-poo method’ (not washing hair) is not advised by trichologists who say that ‘hair doesn’t clean itself’. You could end up with scalp infections. They say ‘pooh-pooh’ to ‘no-poo!’
Green People’s Organic Anti-Dandruff Shampoo
Green People Organic Men’s Shampoo contains pineapple enzymes and aloe vera to calm irritation. Sold in easy-to-recycle sugar-cane packaging, it creates natural foam (coconut and yucca), anti-inflammatory oils of rosemary and tea tree (and quinoa protein to thicken hair).
While everyone sheds dead skin cells on the scalp, people with dandruff experience it more frequently. Common in cold months due to indoor heating, oily dandruff however may be caused by overproduction of sebum, and makes flakes sticky and yellow.
Dandruff is more common in people with eczema or psoriasis, excessive hair styling, and lack of zinc or B vitamins in the diet.
Most anti-dandruff shampoos are made with dodgy ingredients, that are too harsh for your scalp. Most contain salicylic acid, coal tar and other ingredients that can dry your scalp (and dandruff is actually caused by dry scalps, so it makes the issue worse).
Stop watching the TV ads (presenters are being paid lots of money!) and instead switch to a good organic shampoo.
