The Grandpa Soap Company has introduced a new line of haircare products designed to address different hair and scalp issues.

Pine Tar scalp-therapy shampoo and conditioner is manufactured from pine tar and tea tree oil to help fight dry and itchy patches on the scalp.

Buttermilk is designed for dry, damaged and colour-treated hair, while Rosemary and Rose clay is said to help rejuvenate hair and restore shine.

“We are excited to reveal our new line of shampoos and conditioners to families who are seeking responsibly made and naturally formulated personal care products.”

Witch-Hazel is claimed to remove dirt and oil residue.

The Grandpa Soap Company co-CEO Katherine Jarnigo said: “As a mum, I understand how difficult it can be to keep a home free of unnecessarily toxic cleansers.

“We are excited to reveal our new line of shampoos and conditioners to families who are seeking responsibly made and naturally formulated personal care products.”
