Start here
Hydrotherapy is a step, not a booking
You cannot book hydrotherapy on its own at D4 Season. It is not a line on our menu. It is a step that sits inside certain head spa treatments. So the real question is which treatment to pick. Hydrotherapy here means warm water flowing gently over your scalp.
It is also not a bath and not a pool. Nobody sits in water. This happens to your scalp while you lie back and rest. Our head spa menu lists every treatment with its exact time and price.
Why people search for the word
Hydrotherapy is a word people meet on other spa websites. It can mean many things elsewhere. At D4 Season it means one thing. Warm water flows gently over your scalp.
The short list
The three treatments that include hydrotherapy
Only three treatments on our menu include hydrotherapy. Here they are, with the exact name, time and price for each one. If a treatment is not on this list, it does not include the water step.
The third one is the Luxury Head Spa, 90 min, $135. It includes a head massage, a deep scalp cleanse, a hair repair treatment, an upper shoulder and arm massage, hydrotherapy, and a blow-dry.
Classic Head Spa (Short Hair Only), 45 min, $70
This is the shortest treatment that includes hydrotherapy. It covers a scalp massage, shoulder and neck relief, a deep-cleansing shampoo and conditioner, hydrotherapy, and an optional blow-dry. The name is literal, so please pick something else if your hair is long.
D4 Signature Head Spa, 60 min, $85
This one runs a full hour and works for any hair length. It covers a head massage, a scalp cleanse, a shampoo and conditioner treatment, an upper shoulder massage, hydrotherapy, and a blow-dry. It is the hour-long version of the same idea.
Just as important
Treatments that do not include it
Several of our longer treatments have no hydrotherapy step at all. That surprises people, so we want to say it plainly. A higher price does not mean more water.
The Aura Scalp Treatment 75 min $110 does not include hydrotherapy. Neither does the Purifying Scalp Care 90 min $168. Neither does the Scalp Revitalize Therapy 90 min $220. Nor does the Chinese Herb Head Spa 60 min $90. Those treatments are built around other steps instead.
So check before you book. If the water step is your reason for coming, say so on the phone. You can also compare the hands-on options on our scalp massage page.
The 90-minute treatments are not all the same
Six treatments on our menu run 90 minutes. Only one of those six includes hydrotherapy, and that is the Luxury Head Spa 90 min $135. Length and price tell you nothing about the water step.
An honest limit
What hydrotherapy will not do
Hydrotherapy is a comfort and cleansing step. It is not medical care. It will not treat a scalp condition, and we do not claim that it will.
See a dermatologist first if your scalp is sore, painful or very flaky. We are glad to see you after that. For a plain walk-through of a full session, read what happens during a head spa.
Speak up during your treatment
Tell your therapist right away if anything feels off. You never have to wait until the end. We can adjust or pause at any point.
