From The Manufacturer

pH 5.5 PROTECTION: To have strong, healthy hair you must keep your scalp’s pH at ~5.5, and that’s what our shampoo and conditioner does. While most so-called all natural shampoo and conditioner sets rely on harsh chemicals, we’re the only vegan shampoo and conditioner to use the precious Soapberries as the naturally pH 5.5 foaming agent. This protects oily hair and is ideal for dry, sensitive scalps that are prone to issues. FRESH, REAL PEPPERMINT: Most organic shampoo and conditioner sets out there aren’t really all natural. Tree To Tub’s different because our products are literally harvested from nature! Instead of using cheap and often toxic artificial fragrances found in common natural shampoo and conditioner sets, we only use the luxurious and reinvigorating Peppermint Essential Oil in this shampoo and conditioner for sensitive scalps. ORGANIC INGREDIENTS FOR A GENTLE TOUCH: For millennia, the indigenous people of Asia have been using the Soapberry because of its naturally balancing properties for ceremonial cleansing and Ayurvedic nourishment. By combining the Soapberry with rich antioxidants and the intense hydration of Organic Moroccan Argan Oil, we created a shampoo and conditioner set that leaves your hair soft and shiny while nourishing your scalp––without any irritation! CLEAN, PURE, WHOLESOME: All our products are free from harsh chemicals (SLS, Parabens, Silicone, DEA/MEA, Gluten). That’s just the minimum requirement at Tree To Tub. This hair care duo is also free from artifical fragrance and is Vegan, Cruelty Free, and Fair Trade. And yes, our Soapberries are sustainably foraged in Taiwan!


You’ve probably seen the term “sulfates” on various products, including shampoos, but what the heck is a sulfate, anyway?

Sulfates make shampoos bubbly, and they fall under the category of surfactants. This group also includes emulsifiers, foaming agents and detergents. Sulfates attract oil and water, helping to remove dirt and dead skin cells from your hair and scalp. By doing this, they can also strip away natural oils, leading to dry, brittle hair.

People with sensitive scalps can also experience itching, dryness and redness from sulfate exposure. Sulfate also has a bad reputation (especially sodium lauryl sulfate) for causing cancer, but sources like the American Cancer Society say that it is not a known carcinogen.

Still, since sulfate is technically a detergent, it can be harsh on your hair, and you might want to choose sulfate-free hair products for this reason.

Many hair care professionals feel that sulfates strip color from treated hair, and that these products are also not good for dry or fine hair. Those who have frizzy and curly locks can benefit from the added moisture that sulfate-free products offer; these are also recommended for people with eczema and sensitive skin.

You will notice that sulfate-free shampoos do not lather up like sulfate-containing ones do, but this does not mean that your hair is not getting clean. It is not necessary to use more shampoo, since your hair will still get clean. You simply need to massage it into your scalp a bit more rigorously.

Products that contain coconut oils are a good sulfate-free option, and there are some good vegan-friendly choices, as well. Sulfate-free shampoos come in all different price ranges, and you can buy larger containers to save money.

Buying Advice

  • Not sure if your products contain sulfate? Look on the ingredients list for: sodium lauryl sulfoacetate, sodium laureth sulfate, disodium laureth sulfosuccinate and other items that begin with the word “sodium.”
  • If you are considering switching over to sulfate-free shampoo, buy small bottles of one company’s shampoo and conditioner and give them a month to see results. Then you can make a more informed decision about what works best for you.
  • Next time you’re at the salon, ask your stylist to check your scalp. If it’s dry or red, sulfate-free products may be the answer.
