Renu Hair Mask (Singapore)

Renu Hair Mask is a deep conditioning treatment that repairs and strengthens damaged hair in a single 10–15 minute weekly session. Designed for hair that has been weakened by chemical processing, heat styling, chlorine, or the cumulative effects of daily washing in hard water, it delivers concentrated moisture and protein to rebuild strand integrity. At S$32 for 100 ml, each tube provides approximately 8–10 weekly treatments for shoulder-length hair.

What Makes Renu Hair Mask Different

Daily conditioners maintain hair between washes. A mask goes deeper — it is a concentrated, extended-contact treatment that penetrates the hair cortex where daily conditioners only coat the surface. Renu Hair Mask uses a rich formula with a 10–15 minute processing time that allows actives to bond with damaged keratin structures inside the strand rather than just smoothing the outer cuticle.

In Singapore, hair damage comes from every direction. Salon culture here is intense — rebonding alone subjects hair to temperatures above 180°C and strong alkaline solutions that break and reform disulphide bonds. Add regular colour treatments, keratin straightening, and the occasional digital perm, and most hair has been through significant chemical stress. On top of that, daily washing (often twice in hotter months), chlorine from pool swimming at condo facilities, and UV exposure from being outdoors all contribute to protein loss and dryness. The mask addresses accumulated damage rather than surface-level dryness.

Key Ingredients

Hydrolysed Keratin is the primary repair agent — these are keratin protein fragments small enough to penetrate the hair cortex and fill in gaps left by chemical and heat damage. The result is measurably stronger hair with improved elasticity: treated strands resist breakage better during brushing and styling. For hair that snaps when pulled through a comb after rebonding, this makes a noticeable difference within 2–3 treatments.

Shea Butter provides deep lipid moisture that softens brittle hair and reduces static — useful in air-conditioned environments where humidity drops to 40–50%. Argan Oil adds a natural moisture seal without the synthetic heaviness of silicones, which is preferable for colour-treated hair where silicone buildup can dull vibrancy over time.

How to Use

After shampooing, squeeze out excess water. Apply a generous amount (about a 50-cent coin-sized dollop for shoulder-length hair) from mid-lengths to ends, concentrating on the most damaged areas — typically the ends and any sections that have been colour-treated or heat-styled. Comb through with a wide-tooth comb to distribute evenly. Leave on for 10–15 minutes. For deeper conditioning, wrap hair in a warm towel or use a shower cap — the trapped heat opens the cuticle further and improves penetration.

Use once weekly as a standard maintenance treatment. If your hair has recently undergone a chemical service (rebonding, colour, perm), use twice weekly for the first 2–3 weeks post-treatment, then revert to weekly. There is no need to follow with a separate conditioner — the mask replaces your conditioner on the days you use it.

Frequently Asked Questions

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

Can I use this on rebonded hair?
Yes, and it is especially recommended for rebonded hair. The rebonding process breaks and reforms protein bonds, leaving hair structurally weakened. The hydrolysed keratin in this mask helps fill those gaps. Wait at least 72 hours after a rebonding treatment before first use.

Is it too heavy for fine hair?
For very fine hair, use a smaller amount (20-cent coin size) and apply only to the ends, avoiding the roots and mid-lengths. Rinse thoroughly. The formula is rich but rinses clean without residue when used as directed.

How often should I use it?
Once weekly for maintenance. Twice weekly for the first 2–3 weeks after chemical treatments. Over-masking (daily use) can lead to protein overload, making hair feel stiff rather than soft.

Can I leave it on longer than 15 minutes?
Yes. Leaving the mask on for up to 30 minutes is safe and can improve results, particularly on very damaged hair. Leaving it on overnight is not recommended as extended protein exposure can make hair brittle.
