Is the LUNA 4 Hair a hair mask?

No. It is a scalp massaging and cleansing device. It is meant to be used with your own oils, serums or treatments, not instead of them.

Does the red LED light regrow hair?

FOREO claims the red LED combats thinning and breakage. There is no independent proof it regrows hair, so treat it as a support to your routine, not a treatment.

Can I use it in the shower?

Yes. It is fully waterproof and quick-drying, so it fits a shower routine. Rinse and dry it after use.

How does it compare with a plain scalp brush?

It adds T-Sonic vibration and red LED light to the silicone bristles. A plain brush only scrubs, so the LUNA 4 Hair offers more modes but needs charging and costs more.

What comes in the box?

The device and a serum are included, along with a USB charging cable.

Anyone with a very sensitive or irritated scalp, or anyone expecting a guaranteed fix for hair loss, should not rely on it.

Our take on the Foreo LUNA 4 Hair

The FOREO LUNA 4 Hair is a rechargeable, waterproof scalp tool that combines T-Sonic pulsations with red LED light. Its 395 soft silicone bristles part hair and lift oil and product buildup, while the massage is meant to boost microcirculation at the follicle. It suits people who already use oils or serums and want a shower-friendly scalp step; it is a massager, not a hair mask or a proven hair-growth treatment, so judge it against simple scalp brushes and other LED combs on comfort and consistency of use.
