MAC Styler MC-5591 PRO+ Sikly Haircare professional flat iron in Starry Grey, featuring a 1.8-inch plate, MCH heater with 30-second rapid heat-up to 480°F, infrared negative ion hair care technology, one-click temperature control (180–480°F, 10°F increments), temperature lock, programmable auto shutdown, Curl and Straight 2-in-1 function, and premium leather gift box packaging. Available in Starry Grey, Bright Red, and Ink Black. Global voltage 110–240V.

The MAC Styler MC-5591 PRO+ Sikly Haircare is the Starry Grey variant of the PRO+ Sikly Haircare straightener series — sharing the full technology platform of the MC-5590 with a distinct Starry Grey metallic finish that delivers a refined, gender-neutral aesthetic suited to both professional salon environments and premium retail gifting channels.
The MC-5591 carries every defining specification of the PRO+ Sikly Haircare platform: a 30-second rapid heat-up to 480°F via the MCH heater combined with an infrared heating element; the visible red-orange infrared strip between the plates that actively delivers infrared energy into the hair shaft during styling; a built-in negative ion generator for cuticle sealing and frizz elimination; and a 1.8-inch plate width that serves both straightening and curl/wave styling equally well.
The temperature control system is identical to the MC-5590: + and - buttons adjust in precise 10°F increments from 180°F to 480°F; a light press of the circular power button locks the current temperature to prevent accidental changes mid-session; and a full press of the power button cycles through programmable auto-shutdown intervals for safety and energy efficiency.
The Starry Grey colourway of the MC-5591 positions it as the most versatile of the three PRO+ Sikly Haircare colour SKUs in terms of retail placement — the neutral metallic grey tone is appropriate for unisex gifting, professional salon retail, minimalist premium beauty channels, and markets where a non-saturated colour story is preferred over the bold red of the MC-5590 or the classic black of the Ink Black variant.
Each MC-5591 ships in a coordinated black leather gift box with a botanical-pattern wrap band — a premium, shelf-ready presentation that requires no additional retail packaging. The complete product identity — Starry Grey iron in black leather gift box with botanical wrap — creates a visually coherent, premium unboxing experience that supports the PRO+ Sikly Haircare brand position.

For B2B buyers, the MC-5591 Starry Grey is typically the most versatile SKU for:
(1) multi-SKU retail assortments where both a bold colour and a neutral colour are needed;
(2) unisex or male-accessible salon tool retail;
(3) premium gift channels where a sophisticated neutral tone is preferred.
The Starry Grey and Ink Black variants are both available under the MC-5591 model family; the Bright Red is the MC-5590. All three can be ordered and shipped together as a colour-coordinated PRO+ Sikly Haircare collection.
The MC-5591 operates on the same PRO+ Sikly Haircare technology platform as the MC-5590. Key platform differentiators versus the core MAC Styler range:
The MC-5591 infrared heating element is the central technology upgrade of the PRO+ Sikly Haircare platform. The visible infrared strip glows red-orange between the plates during operation and delivers three measurable benefits:
The negative ion generator works simultaneously: emitting ions that neutralise static charge, smooth raised cuticle scales, eliminate flyaways and frizz, and add a mirror-like shine to the styled hair. The combination of infrared penetration and ionic sealing is described as 'Infrared negative ion hair care' in product positioning — a hair care function that extends beyond simple heat styling.
The MC-5591 temperature management system is the most sophisticated in the MAC Styler range, with three distinct functions accessible from the control panel:
Function |
Action |
Purpose |
Temperature Adjustment |
Press + (increase) or - (decrease) — 10°F steps |
Precise targeting for different hair types and sections |
Temperature Lock |
Press the power button lightly |
Locks set temperature — prevents accidental adjustment during styling |
Auto Shutdown Timer |
Click power button (full press) to set shutdown time |
Auto power-off after set interval — safety and energy saving |
Three temperature zones illustrated in product imagery for user guidance:
Temperature Zone |
Hair Type |
180°F – 230°F |
Soft, fine, or delicate hair — lowest heat zone for fragile, chemically treated, or bleached hair |
280°F – 360°F |
Normal hair — standard everyday straightening and wave styling range |
420°F – 480°F |
Coarse, thick, or resistant hair — maximum heat zone for stubborn textures and keratin treatments |

The Starry Grey finish of the MC-5591 is a key retail and visual differentiator within the PRO+ Sikly Haircare three-SKU colour story:
The Starry Grey colourway is the most commercially versatile in the PRO+ Sikly Haircare range. It photographs well in both bright and moody lighting — supporting both product page imagery and social media content creation for retail marketing partners.
The MC-5591 Starry Grey ships in a coordinated black leather gift box — the same premium format as the MC-5590 but with a black leather exterior and matching botanical-pattern wrap band, coordinated to the neutral-to-dark aesthetic of the Starry Grey iron.
The black leather gift box positions the MC-5591 Starry Grey for: unisex gifting, corporate beauty gifts, salon retail display, and premium e-commerce channels where the product image conveys gift quality. No additional gift wrapping or outer box is required for retail-direct sale.

The MC-5591, identical in hardware to the MC-5590, delivers the same four demonstrated hair outcome categories:
Step 1 – Power On: Press the circular power button (blue LED ring illuminates). LCD displays the current or last-used temperature.
Step 2 – Set Temperature: Press + or - to adjust in 10°F increments. Zones: 180–230°F for fine/soft hair; 280–360°F for normal hair; 420–480°F for coarse/thick hair.
Step 3 – Wait (~30 Seconds): MCH + infrared dual heating reaches 480°F in approximately 30 seconds. The infrared strip glows orange-red confirming active infrared operation.
Step 4 – Lock Temperature (Optional): Press the power button lightly to lock the set temperature. The lock symbol illuminates on the display.
Step 5 – Set Auto Shutdown (Optional): Click the power button (full press) to cycle through and set an automatic shutdown timer.
Step 6 – Style (Straightening): Clamp a 1.5–2cm section of hair between the plates. Glide smoothly from root to tip. Infrared energy penetrates the shaft; negative ions seal the cuticle simultaneously.
Step 7 – Style (Curling/Waves): Clamp a section, rotate the iron 90–180°, and pull through at a controlled speed. Adjust rotation angle for tighter or looser results.
Step 8 – Power Off: Press power button to turn off, or allow the auto-shutdown timer to activate. Cool on a heat-resistant surface before storing.

A: The MC-5591 (Starry Grey) and MC-5590 (Bright Red) are sister models on the same PRO+ Sikly Haircare platform. They are identical in every technology specification — plate width (1.8 inch), heat-up speed (30 seconds), temperature range (180–480°F), infrared technology, negative ions, temperature lock, auto shutdown, and 10°F step increments. The only difference is body colour and coordinated gift box: MC-5591 is Starry Grey with a black leather box; MC-5590 is Bright Red with a red leather box. An Ink Black colour variant is also available under the MC-5591 family.
