Laifen Swift 4 High-Speed Hair Dryer | Lavender (Standard Nozzle + Nourishing Nozzle included) (LFHD-SWIFT4-LV)

58°C Golden Temperature Control – Disperses hair oil treatment into the hair strands

Using high-speed, stable airflow, the liquid hair oil treatment is instantly dispersed into nano-sized particles. Paired with the 58°C golden temperature-control “essence infusion” mode, the oil is heat-activated to fill and repair damaged areas of the hair cuticle-boosting moisture. It delivers both drying and hair care at the same time: two effects in one device.

Double the moisture – Faster, more convenient

With the premium essence-infusion nozzle and mode, the hair-care routine is integrated into the blow-drying process. It solves the hassle of traditional routines that require applying hair oil separately, making hair care more efficient.

Custom Hair Oil – Replace Anytime, Anywhere

Switch between different hair oils anytime to match different hair types and needs.

3 Steps to Easily Nourish Silky Hair:

(1) Open the magnetic cover plate of the essence-infusion nozzle. Add 2–3 pumps or 5–6 drops of hair oil onto the white sponge in the essence capsule. After the oil is fully absorbed into the sponge, close the cover.

(2) Blow-dry hair until it is about 80% dry, then switch to the essence-infusion nozzle.

(3) Turn on Essence Infusion Mode to start the care routine.

(Recommendation: Add hair oil once every 2 weeks (no need to add it every day). Replace the essence capsule once every 3 months.)

Note: Do not turn on the hair dryer while installing the dryer body/nozzle.

Positive & Negative Ions – Dual-Effect Combination

Upgraded to 400 million negative ions and 70 million positive ions to build a healthier hair-care foundation, neutralize static electricity, and repair the cuticle layer – making hair noticeably smoother and more manageable.
