With this line brings the second time this year I’ve heard about the topic of pH and hair care products, as in, keeping the pH level of shampoo and styling products between a certain range will help keep treatments longer. Why is this good? From what I understand, a product’s pH plays a big factor in how long your hair color or treatment stays in the strands. When you have hair color put in for example, the cuticle must be opened up to deposit the formula, and it must be above a 5.5. So if you use a shampoo and other styling products that have a high pH, you are opening the cuticle and removing the color/treatment every time you use them. Makes sense.

When I met with the very knowledgeable Cindy from Zerrans here, they were the first ones to bring this fact up to me and their line is also pH-friendly. So now you’re probably wondering how the products you currently have in your bathroom will fair. If you’re up for it, Cindy says to get some litmus paper and test them. Yup, the same litmus paper you used to use in science class, and test your shampoos and conditioners. Bring on science class 101 again! Anyway, back to the products. The line is called SOJOURN and was created by Vidal Sassoon’s son Elan, so you know he knows something about hair, right? He studied the hair in its natural state and determined that the idea pH range is 4.5 to 5.5 so all the products fall in that range or lower. And they also incorporate keratin into the formula with what they call Keratin Cashmere Protein to really help moisturize strands and keep it strong. The line is also 100% biodegradable and free from parabens, formaldehyde, and sulfates.

And he’s made it easy for us to get the most out of the line by breaking it into four different collections – Smooth (the peach bottles), Moisture (the sky blue bottles), Volume (the moss colored bottles) and the one I tried, Colour Preserve (the ivory bottles shown here). Prices range between $20 and $26 @ amazon.com.
