Item 5140 | Short Bob Wig with Bangs and Heat Defiant Fiber

Lace Front Short Bob with Heat-Resistant Styling Freedom and Natural-Looking Movement

The Heat by Jon Renau (Item 5140) is a short bob wig with bangs designed for women who want everyday styling versatility without sacrificing comfort or a natural-looking result. Part of Jon Renau's HD (Heat Defiant) Collection, Heat features a SmartLace® lace front, Heat Defiant synthetic fiber rated safe for heat styling up to 270–280°F, and low-permatease construction that keeps the silhouette polished and believable all day long.

Why Choose the Heat Wig?

Heat is built for women who want a refined short bob they can actually style — not just wear as-is. Its Heat Defiant fiber allows curling, straightening, waving, and finger-styling as often as needed, giving you the kind of day-to-day flexibility that standard synthetic wigs simply cannot offer. The SmartLace® front creates an undetectable hairline that disappears against the skin, supporting off-the-face styling and a completely natural-looking front edge.

At just 2.8 ounces, Heat is genuinely lightweight for all-day wear. And its low permatease, medium-density construction keeps the bob looking refined and natural rather than overly voluminous or obviously structured — a quality that makes it one of the more believable short wig styles in the Jon Renau lineup.

Construction Breakdown: What Makes Heat Different

SmartLace® Front — Jon Renau's proprietary lace front technology creates a sheer, skin-blending hairline that lies flat against the forehead for a completely undetectable front edge. The SmartLace® front supports styling the hair away from the face without exposing an artificial hairline.

Heat Defiant (HD) Fiber — Heat's HD synthetic fiber is engineered to withstand heat styling tools up to 270–280°F — allowing curling irons, flat irons, and hot rollers to be used freely on the style. The fiber holds style memory, meaning the shape set with heat tools stays in place until you choose to restyle.

Low Permatease Construction — Unlike wigs that rely on heavy internal teasing to create volume, Heat uses low permatease with medium density. This creates natural-looking body and movement without the puffy, overly rounded silhouette that high-permatease wigs can produce.

O'solite® Lightweight Construction — Jon Renau's O'solite® cap engineering minimizes overall wig weight, contributing to Heat's comfortable 2.8 oz wearing weight for extended all-day comfort.

Heat Styling Guide

Heat by Jon Renau's HD fiber gives you real styling flexibility — but a few best practices will protect the fiber and ensure the best results every time.

Temperature — Always start at a lower setting around 230°F. Test on a small strand before proceeding. Increase gradually toward 270–280°F only as needed. Never exceed the 270–280°F upper limit.

Heat Protectant — Always apply a heat protectant spray formulated for synthetic fiber before any tool contact. This is the single most effective habit for extending fiber life with regular heat styling.

Cooling — Allow the fiber to cool completely after heat styling before touching, brushing, or wearing. The style sets as the fiber cools — handling it before it's fully cool disrupts the shape.

Tools — Curling irons, flat irons, and hot rollers are all compatible with Heat Defiant fiber within the safe temperature range.

Care Instructions

Washing — Wash every 8 to 15 wears using shampoo and conditioner formulated specifically for synthetic wigs. Cool water only — never hot. Gently swish and rinse without scrubbing or wringing.

Detangling — Finger-style or use a wide-tooth comb only when the fiber is damp or cool. Never comb through dry, tangled fiber from the root down — always start at the ends and work upward gradually.

Drying — Air dry on a wig stand after washing. Never apply heat to a wet wig. Allow the style to reform naturally as the fiber dries.

Storage — Store on a wig stand between wears to protect the bob shape and prevent tangling and compression.

Available Colors

Heat is available in a warm, versatile palette of five shades spanning deep brunettes to golden blondes: 6/33 Raspberry Twist, FS4/33/30A Midnight Cocoa, 6F27 Caramel Ribbon, FS26/31 Caramel Syrup, and 12FS8 Shaded Praline. Colors shown include FS6/30/27, FS4/33/30A, 6/33, and 6F27.

Frequently Asked Questions

Is the Heat wig actually heat-friendly? Yes. Heat Defiant (HD) fiber is rated safe for heat styling tools up to 270–280°F. Always start at 230°F, test a strand, use a heat protectant, and allow the fiber to cool fully after styling to lock in the shape.

What is SmartLace® and how is it different from a standard lace front? SmartLace® is Jon Renau's proprietary lace front technology — a finer, more refined lace construction engineered to lie flatter against the skin and blend more convincingly with a wider range of skin tones than standard lace front panels. The result is a more consistently undetectable front hairline across different complexions and lighting conditions.

What is Heat Defiant (HD) fiber? Heat Defiant fiber is Jon Renau's proprietary heat-resistant synthetic fiber engineered to withstand styling tools within the 270–280°F range without melting, fusing, or losing its shape. It also holds style memory — the shape set with heat tools remains in place until you restyle with heat or washing.

What does "low permatease" mean and why does it matter? Permatease refers to internal teasing built into a wig's construction to create volume at the roots. High permatease creates significant lift that can look artificial and puffy. Heat's low permatease construction produces natural-looking body and movement without the obviously volumized silhouette — keeping the bob believable and refined rather than rounded and dense.

Who is Heat best suited for? Heat is ideal for women who want a polished, everyday short bob with real styling flexibility. It suits women experiencing hair loss from alopecia, chemotherapy, or other causes who want a natural-looking lace front and a lightweight, comfortable daily option. It's also well-suited for women who've found standard synthetic wigs limiting because they couldn't be heat-styled or refreshed between washes.

How does Heat compare to standard synthetic short wigs? Standard synthetic short wigs cannot be heat-styled — the fiber will melt or fuse at heat tool temperatures. Heat's HD fiber removes that limitation entirely, giving you curling irons, flat irons, and hot rollers as everyday styling tools. Combined with the SmartLace® front and low permatease construction, Heat offers a significantly more versatile and natural-looking result than comparable standard synthetic styles.

Is Heat a good option for women experiencing hair loss? Yes. The SmartLace® front creates an undetectable hairline, the low permatease design keeps the silhouette natural-looking, and the 2.8 oz weight is gentle enough for sensitive scalps during extended daily wear. The lace front construction also allows styling away from the face, giving more flexibility in how the wig is worn and positioned for maximum confidence.
