ageLOC® Nutriol® Scalp & Hair Serum (Singapore)

ageLOC Nutriol Scalp & Hair Serum is a leave-in treatment that delivers Tricalgoxyl — a seaweed-derived complex — directly to the scalp, targeting the root environment where thinning begins. Applied twice daily, it supports thicker-looking hair over a 90-day cycle without any need to rinse. At S$65 for a 75 ml bottle, it lasts approximately 6–8 weeks with consistent use.

What Makes ageLOC Nutriol Serum Different

Most hair serums sit on the hair shaft and address surface-level dryness. Nutriol Serum bypasses the strand entirely and works at the scalp. The formula uses a targeted dropper applicator that delivers the serum precisely to the areas that need it — along the part line, at the temples, or wherever thinning is most noticeable. In Singapore, where daily washing strips the scalp of natural oils and air-conditioning dries it further, a leave-in scalp treatment maintains consistent nourishment between washes.

The serum is non-greasy and absorbs within 2–3 minutes, which matters when you are heading into 85% humidity and do not want a slick residue weighing hair down. It layers under styling products without interference, so it fits into morning routines before work without adding extra time.

Key Ingredients

Tricalgoxyl is the core active — a complex derived from brown seaweed (Undaria pinnatifida) that has been studied for its ability to support the hair follicle environment. In Nu Skin's testing, participants using Tricalgoxyl-based formulas reported visibly fuller-looking hair after 90 days of consistent use. The ingredient works by helping to condition the scalp and maintain a healthy follicle environment rather than stimulating growth directly.

Tocopherol (Vitamin E) provides antioxidant protection to the scalp, which is relevant in Singapore where UV exposure is high year-round (UV index regularly hits 11–12). Panthenol (Pro-Vitamin B5) adds moisture retention to the scalp surface, helping to counteract the drying effects of frequent shampooing — something most Singaporeans do daily.

How to Use

Apply 1–2 ml directly to the scalp using the dropper applicator, focusing on areas of concern — the crown, temples, or part line. Massage gently with fingertips for 30–60 seconds to aid absorption. Use twice daily: once in the morning before styling, and once at night before bed. Do not rinse out. For best results, use consistently for a minimum of 90 days, as hair growth cycles mean visible changes take time.

If you wash your hair in the morning (common in Singapore given overnight perspiration in warm weather), apply the serum after towel-drying and before any heat styling. The lightweight formula will not interfere with blow-drying or flat-ironing.

Frequently Asked Questions

How is this shipped in Singapore?
All orders ship from the official Nu Skin Singapore warehouse. Standard delivery costs S$4.99, or free on orders over S$99. Expect delivery within 1–3 business days to any Singapore address.

Will this make my hair look greasy?
No. The serum absorbs into the scalp within 2–3 minutes and leaves no visible residue. It is specifically designed as a leave-in treatment, not a styling product.

Can I use this with chemically treated hair?
Yes. Whether you have had rebonding, keratin treatments, or colour processing, the serum is applied to the scalp rather than the hair shaft, so it does not interfere with chemical treatments.

How long does one bottle last?
At the recommended twice-daily application of 1–2 ml, a 75 ml bottle typically lasts 6–8 weeks depending on the size of the area you are treating.

When will I see results?
Hair growth cycles run approximately 90 days, so Nu Skin recommends at least 3 months of consistent use before evaluating results. Some users notice less hair fall within the first 4–6 weeks.
