other ingredients we might use in a shampoo, and these are the ingredients that we would modify or leave out when considering about designing a shampoo to be used in a line with other products. Do we need conditioning agents in a shampoo if we're using a conditioner afterwards? Do we need to worry about moisturizing or using a humectant? Do we want to include extracts and such?
I have given this much thought and I would argue that yes, there are many reasons to use these ingredients in a shampoo to take it from okay to awesome even if you are following up with a conditioner. We'll take a look at a few of these ingredients over the next few days.
I encourage you to stop here and read this post on increasing mildness in our products, rather than having me re-copy everything here. The summary is this - we use different ingredients to increase mildness in our products and reduce the irritation or dryness that might come with only using surfactants on our skin and hair. This explains another concept we'll be discussing a lot in the near future, which is combining surfactants to get a milder blend.
I would also like to suggest that you stop here and read about how we can increase the viscosity of our products using ingredients like Crothix, Ritathix DOE, and glycol distearate.
Welcome back! As you can see, although we might think of an ingredient like hydrolyzed oat protein as having one purpose - forming a film on a hair strand to increase moisturization - it can also increase the mildness of the product, increase the viscosity of the product, or make it a better a cleanser. This is why we should spend some time getting to know our ingredients and how they behave in a shampoo!
