What Are Hair Growth Injections?

Hair Growth Injections are minimally invasive treatments that place active ingredients directly into the scalp where hair follicles are located.

Depending on your treatment plan, injections may include:

• Platelet-Rich Plasma (PRP)
• Hair Mesotherapy
• Exosome Therapy
• Stem cell-derived conditioned media
• Peptides
• Vitamins
• Amino acids
• Growth factor formulations

These treatments are commonly recommended for:

• Male pattern hair loss
• Female pattern hair loss
• Early hair thinning
• Diffuse hair loss
• Excessive hair shedding
• Hair maintenance after transplantation

Hair Growth Injections are most effective when active hair follicles are still present.

How Hair Growth Injections Work

Injectable therapies deliver regenerative or therapeutic ingredients directly into the scalp.

Depending on the product used, treatment may help:

• Stimulate dormant hair follicles
• Improve scalp circulation
• Support healthier follicle function
• Reduce inflammation
• Decrease hair shedding
• Improve hair thickness
• Increase hair density

Because hair loss has many causes, dermatologists often combine injectable treatments with medications or other therapies for optimal results.
