So how do you deep condition? And how do you know if your deep conditioner is good or not? Do you rely on price? Not necessarily as an expensive product doesn’t mean the product is good, nor does a cheap product mean it doesn’t work. So what should you look for? The answer to this question is to become ingredient savvy. Having an understanding of ingredients will help you determine, at least at first glance, if a deep conditioner is going to be effective for you or not.
Ingredients that attach onto to the hair
Remember we discussed the fact that conditioning agents ADSORB to the hair? ADSORBING means that the ingredients attach to the surface of the hair. This phenomenon is responsible for helping to soften the hair, temporarily repair the hair, smooth the cuticle and reduce flyaways. The main types of ingredients you’re looking for are cationic surfactants, cationic polymers, emollients, oils and silicones.
Surfactants are molecules that have water-loving and water-repelling segments. There are many uses for surfactants and they are mainly used for their cleansing ability. Surfactants can carry a positive charge, negative charge or no charge. However, when it comes to conditioning, cationic surfactants – or those with a positive charge – are extremely important. Since hair carries a relative negative charge, if you use a cationic or positively charged surfactant it will be attracted to the negatively charged section of the hair and bind to the surface of the hair. The surfactants will also form a film that smoothes the cuticle resulting in reducing static, tangling and improving softness. What are some main cationic surfactants? Behentrimonium methosulfate, behentrimonium chloride and cetrimonium chloride. Other ingredients that adsorb are conditioning polymers like the polyquaterniums and cationic guar gum. Lastly emollients such as cetyl and cetearyl alcohol, some oils and silicones also have the ability to attach to the hair and convey benefits.
Ingredients that penetrate into the hair
Some ingredients can penetrate into natural hair at a temperature of about 35 degrees celcius. This corresponds to the temperature that would be reached if you applied conditioner to your hair and covered it with a shower cap. These ingredients include hydrolyzed wheat protein, hydrolyzed silk protein, coconut oil, cetrimonium bromide, panthenol, some silicones. Many can penetrate in between the layers of the cuticle and into the cortex of the hair. Each ingredient has its own time for penetration ranging from minutes to hours. This time can also depend on the condition of the hair often with damaged hair resulting in faster penetration than hair that is not damaged. So what about the DIY mayonnaise, avocado and egg masks so many women use? Well the truth is that a lot of those ingredients aren’t penetrating INTO the hair. Especially not the egg. In order for protein to penetrate into the hair is has to be hydrolyzed into amino acids. Egg protein is just too large to have any affect inside the hair. The most you’re hoping for with these DIY masks is for the ingredients to sit ON TOP of the hair and make your hair feel good temporarily.
So what are the best steps to deep condition curly hair?
After you have effectively deep conditioned your hair it should feel softer, moisturized, shiny and more manageable. If your conditioning treatment results in this then you’ve definitely found a product to keep. If it doesn’t then get rid of it, read the ingredient list and invest in a product that is really going to do something for your hair.
Beware of overconditioning!
Some women love to leave a deep conditioner on their hair for hours at a time for various reasons. While conditioning is good for the hair, too much of a good thing is not necessarily better. Conditioning for hours at a time can result in softer hair and this likely occurs because of a change in the keratin forming a different configuration than normal. Hair that is softer will be weaker and more prone to breaking if manipulated. This change in keratin is temporary and your hair will return to its stronger state but you’ll need to be careful how you handle it until it does.
