Peptide hair growth serum works by delivering a concentrated dose of peptides to the scalp. Peptides are amino acid chains that signal cells to perform specific functions, such as promoting hair growth. When applied topically, these peptides penetrate the scalp, stimulating hair follicles and encouraging the growth of thicker, stronger hair.

Yes, peptide hair growth serum is generally suitable for all hair types, including oily, dry, curly, straight, and chemically treated hair. Since peptides work at the cellular level to promote hair growth, they can benefit anyone looking to improve the health and appearance of their hair.

Results vary depending on individual factors such as genetics, hair health, and consistency of use. However, many users report noticing visible improvements in hair thickness, strength, and overall growth within 4 to 6 weeks of regular use. For best results, it's recommended to apply the serum as directed and to be patient, as hair growth is a gradual process.

Peptide hair growth serums are generally well-tolerated, but like any skincare or haircare product, some individuals may experience sensitivity or allergic reactions to certain ingredients. It's always advisable to perform a patch test before using the serum extensively, especially if you have a history of skin allergies. Additionally, if you experience any adverse reactions such as itching, redness, or irritation, discontinue use immediately and consult a healthcare professional.
