FAQs
The Head Spa offers a unique, refreshing experience that’s new to the U.S., using only luxury ingredients and products in every treatment. Our services are designed to be safe for most clients, though some exceptions may apply. To ensure you have the best experience, please take a moment to review everything you need to know before your first visit!
What are the benefits of a Head Spa?
One of the primary benefits of a Head Spa is deep relaxation. There’s something uniquely soothing about having someone massage your scalp, transporting you to a realm of calm and comfort. At Mercer Head Spa, we go beyond traditional techniques by incorporating pressure-point massages and gua sha tools, which enhance your experience and stimulate your scalp in a rejuvenating way.
In addition to relaxation, Head Spa treatments can help ease tension, calm stress, alleviate TMJ discomfort, reduce migraines, help stimulate hair growth, reduce hair loss, and improve overall well-being. Many clients find that our treatments not only provide relief but also promote a sense of renewal and balance.

It depends on the length of service you booked. So if you are booked for a 60 minute session for example, please plan to arrive at least 5 minutes before and be in our spa for the full time.
At the start of your service, we’ll ask whether you prefer a light, medium, or strong massage. If you feel the need to adjust the pressure during your session, please let your Head Spa therapist know, and they’ll be happy to make the adjustment.
The length of your scalp massage will depend on the service you booked and the duration of it. Refer to our menu options above for more details.

We include a basic blow dry/dry off as part of our head spa service. This will remove excessive moisture from your hair, this will ensure you don't leave our studio with dripping wet hair.
Blow outs, Straightening, Waves, Styling, etc. are currently add-on services that you will have to add at the time of booking.
All of our ingredients are safe for any kind of treated hair! However, if you had recently done any kind of chemical services within a week before your Head Spa appointment, there is a chance that the color/keratin may lift during our detoxing process. Therefore, we recommend customers to wait at least a week after any kind of hair treatment before receiving a Head Spa.
We also recommend waiting at least a week after having a Head spa before doing any kind of chemical services. You wouldn’t want to apply chemicals to a freshly cleaned scalp!
Our specialists are experienced in working with all hair types—whether thin and fragile, thick and coarse, wavy, curly, porous, or even bald. However, the focus of the Head Spa is on the scalp, not the hair itself. As long as you have a scalp, we can provide a treatment! The only requirement is ensuring we have proper access to it. Unfortunately, we cannot perform services on clients with extensions, braids, or sew-ins, as these block access to the scalp and pores.
Our Head Spa uses safe and clean products; therefore, it is completely safe for pregnant customers. However, some guests may be concerned about being exposed to certain herbs and oils such as lavender while they are expecting. Therefore, it would be best to consult your doctor to see if anything you should avoid.
Another concern would be that we require guests to lay completely flat on your back during the whole duration of the service. If this is something you are unable to do, then it may be best to wait until after the delivery before trying the head spa.
Once in the Head Spa room, all cell phone usage will be prohibited. Please set your phone to silent mode and set it aside before starting the appointment. If you do wish to record the treatment for social media purposes, please let us know in advance. We are more than happy to facilitate this for you. Please don’t forget to mention us @MercerHeadSpa!
