Q: Can I use a face serum on my hair?

A: While the active ingredient is the same, a dedicated vitamin C serum for hair is formulated with silicones or oils that are designed to coat the hair shaft without leaving a sticky residue.

Q: How often should I use Vitamin C treatments?

A: For most, a topical treatment 2–3 times a week is sufficient. Over-cleansing with acidic vitamin C shampoos can sometimes lead to dryness if not balanced with a good conditioner.

Q: Will Vitamin C lighten my hair colour?

A: In very high concentrations, Vitamin C is sometimes used as a natural way to strip semi-permanent dye. However, in standard hair care products, the concentration is designed to protect colour, not remove it.

Q: Is it possible to use too much vitamin C on my hair?

A: While it is difficult to "overdose" on vitamin C through diet, topical over-application can lead to a slight shift in your hair’s pH balance. Because vitamin C (ascorbic acid) is naturally acidic, using a highly concentrated vitamin C serum for hair too frequently without a follow-up moisturiser may cause the hair to feel temporarily stiff or dry. Balance is key; always follow an acidic treatment with a nourishing conditioner.

Q: How long does it take to see results when using vitamin C for hair growth?

A: Consistency is your best friend. While you might notice an immediate increase in shine and smoothness after one application of a hair damage solution containing vitamin C, the benefits for growth take longer. Because the hair growth cycle is a slow process, you should typically expect to see a noticeable difference in thickness and strength at the roots after 3 to 6 months of consistent use.

Q: Does vitamin C help with a dry or itchy scalp?

A: Yes, it can be quite beneficial. Vitamin C benefits for hair extend to the scalp due to its role in collagen synthesis and its mild exfoliating properties. It helps to clear away dead skin cells and build-up from styling products that can clog follicles. By maintaining a healthier, clearer scalp environment, it indirectly supports the foundations of healthy growth.
