Hydrolysed proteins in the hair products are definitely worth to look for because they will give you everything what you want for your hair – strength, elasticity, shine and protection.
Quick science behind hydrolysed proteins: Proteins are very large, so in order to make them smaller they have to be hydrolysed, basically cut into short peaces. There are variety of different hydrolysed proteins, such as wheat and keratin (the most popular ones), soya, collagen, silk , caviar and several others. They are all different because they have different molecular weight so it depends what they can actually do to our hair.
Why to use hydrolysed proteins? They can coat your hair and provide protection against heat styling (usually wheat, soya or jojoba), but if they are medium/light weight they can also get inside our hair and provide more strength and elasticity (silk, keratin, quinoa, caviar).
How to know if you hair needs it? If you are constantly using heat to style your hair, if your hair tangles a lot, if you spending a lot of time in sunshine (lucky you!), if you have bleached hair or if in general your hair is very dry hydrolysed proteins can really help you.
When to avoid hydrolysed proteins? Wheat is well known irritant so if you allergic or do not tolerate it well be very careful with the products that might contain hydrolysed wheat. However, we all have very different hair so only you know what actually works for you, but as I said if you know that soya or wheat causes some sort of irritation stay away from it.
My personal opinion – have a mix of all proteins because that way you will add protecting coat to your hair but you will also add extra strength and moisture. Heart to heart, I really like Nexxus conditioner due to high protein content but it also has silicones that stimulate that shine effect, however, it is still a great product to have to add more strength and elasticity.
So next time you are picking up a new hair product goodie check the ingredients list and if you notice hydrolysed keratin, silk, caviar that will certainly will add more strength and moisture, whilst hydrolysed oat, wheat, soya, pea will provide a good protecting coat on your hair.
