As we mentioned, exosomes for hair regrowth are isolated from Umbilical cord mesenchymal stem cells. These stem cells are broadly multipotent and have a potent mixture of several growth factors that can stimulate hair follicles to divide and start the hair cycle. A few growth factors found in them include:

• Insulin-like growth factor-1
• Fibrinogen beta chain
• Insulin-like growth factor binding protein 5
• Vinculin
• Alpha-fetoprotein

These growth factors come together to trigger cellular regeneration by promoting the proliferation of dermal papilla cells. These cells are the mother cells for the hair strands and play a pivotal role in hair regrowth. It’s as if exosomes are whispering ancient secrets to the hair follicles, urging them to awaken and flourish.

In addition to stimulating the growth of dermal papilla cells, exosomes are known to regulate two crucial signaling pathways, namely the SGK3, Msx2, and Wnt pathways. These two signaling molecules are essential to keep the cells in the anagen phase of the hair cycle, resulting in the hair strands growing longer and thicker. Looking at the process from a different perspective, exosomes stimulate the signaling pathways that keep the cells in the anagen phase, so your clients can see long, strong hair.

In order to provide continuous nutrition to the rapidly dividing dermal papilla cells, there is a need for blood vessels to do the same. Here, there has also been a proven role for exosomes in angiogenesis. They have been shown to boost the formation of blood vessels in the scalp. More blood vessels mean more nutrition for the growing hair strands.
