    Frequently Asked Questions

    How do I apply INH G2G Peptide + Biotin Scalp Serum?

    • Use daily on clean, dry, or towel-dried hair & part the target areas into even sections. Tilt your head back & apply 1-2 drops of serum directly to the scalp in each section concentrating on sparse or thinning areas. Use your fingers, or our INH Got to Gua Sha comb to work the serum into the scalp and increase absorption & circulation.  It is a leave-in serum, so no need for rinsing or washing after application (style as usual).

    • When your scalp is dirty or oily, the formula will not perform at its level due to buildup blockage. If you don't wash your hair daily, or if you use dry shampoo, apply before you use products.

    • Apply morning or night. This is a leave-in product, style your hair normally (it’s also a non-comedogenic, non-greasy formula that will not weigh down your style or cause build-up).

    Warning: If irritation occurs, cease use and consult a physician. Use only as directed on unbroken skin. Patch testing prior to use is advised. Keep out of reach of children. Ask your doctor if it's safe to use if you have severe alopecia. Do not use on open wounds. May cause redness on sensitive skin. While most pregnant women can use this product, consult with a doctor before use. Have questions or need more info? Visit inhhair.com to get in touch.

    When can I expect to see results when using INH G2G Peptide + Biotin Scalp Serum?

    INH G2G Peptide + Biotin Scalp Serum can take 3-4 months to show results when applied as recommended, once daily. The hair growth cycle consists of three phases: anagen, catagen, and telogen. INH G2G Peptide + Biotin Scalp Serum can help support an environment for denser, stronger hair during these phases. Each individual circumstance may be different, but the phases in a hair cycle are the same. However, each user may be in a different hair cycle at the time of first use and may see results quicker than others.

    How long will a bottle of INH G2G Peptide + Biotin Scalp Serum last?

    A bottle of INH G2G Peptide + Biotin Scalp Serum lasts most people about 30 days.
    Some people spot treat areas of concern, in which case, it will last longer.

    Will INH G2G Peptide + Biotin Scalp Serum work with my medical conditions?

    The fact is, the root cause of your hair thinning or hair loss may not be able to be remedied with a topical solution. Hair loss is a nuanced issue that could be caused by anything from stress, to diet, to hormones, to your genes. We’ve tested our INH G2G Peptide + Biotin Scalp Serum with people of different ages, those who experienced menopause hair loss, post-partum hair loss after childbirth, and other hair loss circumstances who have reported incredible results.

    INH G2G Peptide + Biotin Scalp Serum’s main purpose is to assist you with a healthy scalp at the follicle level using natural peptides and safe, beneficial ingredients. Topicals like our hair & scalp serum may set up an ideal environment for thicker, denser hair & retention (scalp & hair care with scientifically studied natural ingredients is beneficial for most). However, if you’re concerned about hair loss we always recommend chatting with your doctor or dermatologist first to determine if there are any underlying causes & if this product may be right for you. 

    As for medical conditions like alopecia, Hashimotos, hereditary hair loss or other medical conditions that can cause hair loss, since we're not medical professionals, we cannot give you any specific recommendations. We would suggest that you consult with your doctor to first make sure if the ingredients or if any hair growth serums will be a right fit for you at this time.
