Hair Blocks - Solid Shampoo Bar (85g) for all hair types: Lemon & Rosemary Solid Shampoo Bar | Soap Free, Plastic Free | Plant Based | Natural | Conditioning

Free Shipping

Why We Love It

Plastic-free, zero waste packaging.
Hand-made with premium ingredients.
Soap-free, pH balanced formula.

Main Highlights

PLASTIC FREE SOLID SHAMPOO BAR - As always our products are totally plastic free, with zero waste packaging. Our shampoo bars also have the equivalent active ingredients of 3 bottles of shampoo. Lasts up to 80 washes.
HAND MADE - Our shampoo bars are cold pressed and made by hand here in the UK by us. There’s a huge difference in quality between hand and machine made shampoo bars because hand-made ones can add significantly more quality oils and other ingredients to protect and enrich your hair.
PREMIUM INGREDIENTS - Our solid shampoo bars use a premium delicate soap-free base derived from coconuts (called Sodium Coccyx Isthionate), and add to that we use a plethora or natural enriching oils that make our bars special. There’s coconut oil for dry hair, jojoba oil for nourishing, hemp seed oil for sensitive or itchy scalps, olive oil for conditioning. We also use special ingredients like wheat protein and Provitamin B5 to help strengthen your hair. This range really is the ultimate shampoo bars for ALL hair types.
INSTANT LATHER - Just a stroke or two and Hair Blocks solid shampoo bars foam up into a lathery goodness. You’ll be amazed just how much lather comes out of something so compact.
SOAP FREE SOLID SHAMPOO BARS have a huge edge over soap containing ones. Why? A neutral Ph is imperative for the protection of your hair. Soap is generally alkaline (Ph 8-10) and will dry out your hair. You don’t have to worry about dry hair or transition time with our Ph balanced (Ph5.5) Hair Blocks that leave your hair in amazing condition.
PLANT BASED & NATURAL - The ingredients we use in our solid shampoo bars are all derived from plants so are suitable for both Vegetarians and Vegans. We also do all our product testing on ourselves… never animals, so we’re Cruelty Free too. You’ll also never find SLS, SLES or any other nasty here either.
A RANGE OF SCENTS - Choose from a range of 8 different fragrances to suit your mood, or even select based on colour to match your bathroom. Whichever one you choose, they’ll have the same great ingredients to give you the ultimate hair wash experience.
VALUE FOR MONEY - A larger solid shampoo bar for the price. As the manufacturer of the products, we don’t have to worry about someone else making profit in the middle. Our bars are incredible bang for buck, with premium ingredients and larger size than most at 85g compared to the standard 60g
