ReNu Volumizing Shampoo (Singapore)

ReNu Volumizing Shampoo adds body and lift to fine or flat hair from the cleansing step, giving strands structure before you even pick up a dryer. In Singapore, where 80–95% humidity presses flat hair even flatter within minutes of stepping outdoors, volume is not just about aesthetics — it is about whether your hairstyle survives the walk from the carpark to the office. At S$53 for 250 ml, it provides 6–8 weeks of daily use for short to medium-length hair.

What Makes ReNu Volumizing Shampoo Different

Most volumizing shampoos work by stripping oils aggressively — less oil means less weight, which temporarily creates lift. The problem is that stripped hair becomes dry, static-prone in air-conditioning, and brittle with repeated use. ReNu Volumizing Shampoo takes a different approach: it deposits lightweight polymers onto the hair shaft during washing that create a micro-scaffolding effect, physically lifting hair away from the scalp without removing the natural oils that keep it healthy.

This matters in Singapore for two reasons. First, daily washing is non-negotiable — perspiration from 31–34°C heat makes skipping a wash impractical for most people. A shampoo that relies on stripping will progressively damage hair over weeks of daily use. Second, fine hair in high humidity absorbs atmospheric moisture, which adds weight and collapses any volume created by styling. The polymer scaffolding in this shampoo provides structural support that resists moisture-driven collapse for 3–5 hours, buying you enough time to get through a morning meeting or a brunch outing without completely flat hair.

Key Ingredients

Hydrolysed Wheat Protein is the primary volumizing agent. It bonds temporarily to the hair cuticle during washing, adding a protein layer that thickens each individual strand by approximately 5–10% in diameter. On fine hair, where strand diameter is typically 50–70 micrometres, even a small increase creates noticeable body when multiplied across thousands of strands.

Biotin (Vitamin B7) supports hair strength at the shaft level, reducing the limpness that comes from weak, bendy strands. Stronger strands hold their shape against gravity and humidity better. Panthenol adds flexibility without weight — it penetrates the cortex and attracts moisture internally, keeping hair pliable enough to hold a style rather than going stiff or flat.

How to Use

Apply a 5-cent coin-sized amount to the roots and scalp — this is where volume starts. Massage for 60 seconds, working the product through the crown area where flat hair is most noticeable. Rinse thoroughly; leftover residue will weigh fine hair down and defeat the purpose. For the best volume results, rinse with cool water and follow with ReNu Volumizing Conditioner applied only from mid-lengths to ends (never at the roots on fine hair).

If you style with a blow-dryer, flip your head upside down while drying the roots — this is the oldest volume trick, but combined with the polymer scaffolding from the shampoo, it creates noticeably more lift than either technique alone. For the NS Line crowd who prefer to air-dry before heading to work in the CBD, scrunch hair gently with a microfibre towel and avoid touching it until fully dry — handling wet fine hair flattens it against the head.

Frequently Asked Questions

How is this shipped in Singapore?
All orders ship from the official Nu Skin Singapore warehouse. Delivery is S$4.99, or free on orders over S$99. Standard delivery takes 1–3 business days islandwide.

Will this work in Singapore’s humidity?
It provides 3–5 hours of visible volume in typical outdoor humidity (80–95%). In air-conditioned environments, volume holds significantly longer — often a full working day. The polymer scaffolding resists moisture-driven flattening, but no product can fully prevent volume loss in extreme humidity.

Is it safe for daily use?
Yes. Unlike stripping volumizing shampoos, this formula maintains natural oil levels while adding body. It is designed for the daily washing habits common in tropical climates.

Can I use this on colour-treated hair?
Yes. The gentle cleansing system is compatible with colour-treated, highlighted, and chemically processed hair. It will not accelerate colour fading.

My hair is fine AND frizzy — Smoothing or Volumizing?
If frizz is your primary concern, start with Smoothing. If flatness bothers you more than frizz, Volumizing is the better choice. You can also alternate: Volumizing on work days when you need polished lift, Smoothing on weekends when frizz control matters more.
