Keratin is a protein that is found naturally in the hair, skin, and nails. It is believed to help strengthen and protect the hair, and some hair growth serums contain keratin to promote healthy hair growth.
Biotin is a B-vitamin that is important for maintaining healthy hair, skin, and nails. Some hair growth serums contain biotin to help promote healthy hair growth.
While these ingredients may have some potential benefits for promoting healthy hair growth, it is important to note that there is limited scientific evidence to support the effectiveness of hair growth serums for treating hair loss.
It is also important to be cautious when using these products, as they may contain other ingredients that can cause side effects or interact with medications or underlying health conditions.
If you are considering using a hair growth serum to treat postpartum hair loss, it is important to speak with a healthcare provider for a proper diagnosis and treatment recommendations.
