Types one and two of hydrolyzed collagen do different things in your body. This is made from fish or other animals that have gone through hydrolysis. The collagen taken from animals is typically from bone or fish skins that have been ground up into a powder. Hydrolysis is when water is used to break down layers of chemical bonds. In this case, it breaks down the collagen to a more digestible level. Here is what each type of collagen is known to do.

Type 1:

This type of collagen improves fine lines and skin elasticity. This is the best type of collagen for rebuilding muscles and also to help grow hair and nails. Type one collagen can also help your hair become much thicker by helping open more hair follicles.

What is it?

Keratin is an insoluble protein that gives your skin, nails and hair their strength and structure. They are what protect against damage or trauma.

How does it prevent hair loss & promote hair growth?

Keratin is a naturally occurring protein that smoothens and toughens the hair shaft to make it more manageable. The keratin molecules in your shampoo are absorbed by cells called cuticles, which overlap like shingles on a roof or tiles on a floor for protection against damage from things such as wind or dehydration. While this makes the ends of each strand harden, making them less prone to splitting when brushed through tangles with wet fingers before washing, they also lock up natural oils near the root and cause frizziness because curls can't move freely around one another any longer without getting tangled together if not properly cared for after treatment.

What the Science Says:

A study was done and published in the journal of RSC Advances that supports that the process of using a chemical keratin treatment actually supported hair health. When added to overly damaged hair, it could penetrate the hair fiber and bind to the natural hair proteins.
