Sleep on your back at a 45-degree angle for the first 7-10 nights after DHI. Elevated back sleeping reduces swelling, prevents grafts from pressing against the pillow, and protects the implantation sites created by the Choi Implanter Pen while they heal and anchor into the scalp tissue.

Why Sleeping Position Matters After DHI
During DHI (Direct Hair Implantation), the Choi pen places each graft directly into the scalp at a precise angle and depth. These grafts take 7-10 days to form new blood vessel connections and anchor securely. Until that happens, they can be displaced by friction or pressure.
Sleep is the highest-risk period for accidental graft damage because you cannot control your movements. Rolling onto the transplant area, pressing your face into a pillow, or sliding against the pillowcase can all put pressure on unanchored grafts.
Elevation also serves a second purpose: reducing swelling. Forehead and periorbital (around the eyes) swelling is common after hairline DHI procedures, peaking on days 2-3. Keeping your head above your heart while sleeping allows fluid to drain downward rather than pooling in the forehead.
Best Sleeping Positions by Recovery Phase
Days 1-3: Strict Elevated Back Sleeping
This is the most critical phase. Your setup should look like this:
| Element | Recommendation |
|---|---|
| Angle | 45 degrees (reclined, not flat) |
| Position | On your back only |
| Head support | Travel neck pillow to prevent head rolling |
| Pillow material | Clean, smooth pillowcase (silk or satin reduces friction) |
| Protection | Place a clean towel on the pillow for any drainage |
How to achieve 45 degrees:
- Use a recliner chair (many patients sleep in a recliner for the first 3 nights)
- Stack 2-3 firm pillows to create a wedge shape on your bed
- Purchase a foam wedge pillow (available at most pharmacies)
- Use an adjustable bed frame if available
A travel neck pillow worn around your neck prevents your head from rolling to either side during sleep. This is one of the most effective tools for protecting grafts overnight.
Days 4-7: Elevated Back Sleeping, Slightly Relaxed
After the first three days, swelling begins subsiding and grafts are starting to anchor. You can reduce your elevation slightly:
- Lower the angle from 45 degrees to approximately 30 degrees
- Continue sleeping on your back
- The travel pillow is still recommended but less critical
- A single firm pillow under a wedge pillow works well
Days 7-10: Transition Period
By the end of the first week, most grafts are secure enough to tolerate light contact. During this phase:
- You can begin lowering to a 15-20 degree elevation
- Careful side sleeping may be possible if the transplant is on the front hairline only (not the sides)
- Continue avoiding stomach sleeping
- If you wake up on your side, do not panic. Gently reposition and continue sleeping
Days 10-14: Return to Normal
After day 10, grafts are firmly anchored and most sleeping restrictions can be lifted:
- Normal pillow height is fine
- Side sleeping is generally safe
- Stomach sleeping can resume by day 14 for most patients
- Use a silk or satin pillowcase to minimize friction (good practice even after full healing)
Sleeping Position Quick Reference
| Night | Angle | Back | Side | Stomach |
|---|---|---|---|---|
| 1-3 | 45 degrees | Yes | No | No |
| 4-7 | 30 degrees | Yes | No | No |
| 7-10 | 15-20 degrees | Yes | Cautious | No |
| 10-14 | Normal | Yes | Yes | Cautious |
| 14+ | Normal | Yes | Yes | Yes |
Practical Tips for Better Sleep After DHI
Sleeping in an unfamiliar position is uncomfortable, and many patients struggle with sleep quality during the first week. These strategies help:
Setting Up Your Sleep Station
Prepare your sleeping area before the procedure day so everything is ready when you return:
- Place a recliner in your bedroom, or set up the wedge pillow arrangement in advance
- Have 2-3 clean pillowcases and towels ready (change daily for hygiene)
- Keep water, medication, and your phone within arm's reach so you do not need to get up
- Set room temperature slightly cool (18-20 degrees Celsius) since sleeping elevated can feel warmer
Dealing with Discomfort
- Take prescribed pain medication 30 minutes before bedtime for the first 3-4 nights
- Some clinics provide a mild sleep aid for the first few nights. Ask your surgeon if this is an option
- Avoid caffeine after noon during the recovery period
- Use white noise or calming audio to help compensate for position discomfort
- If you have a partner, consider sleeping separately for the first few nights to avoid accidental contact
Protecting Against Unconscious Movement
Even disciplined sleepers move during the night. Reduce the risk of rolling:
- The travel neck pillow is the single most effective tool for preventing head rotation
- Place regular pillows on either side of your body to create a barrier
- Some patients lightly tape the travel pillow in place (with medical tape, not adhesive that contacts grafts)
- If you are a habitual side or stomach sleeper, the recliner option is strongly recommended for the first 3-5 nights since it is harder to roll in a reclined chair
What If You Accidentally Sleep on Your Grafts?
If you wake up and realize you rolled onto the transplant area, do not panic. Gently reposition onto your back and check for any signs of bleeding or displaced scabs. A single incident of brief side contact after day 3-4 is unlikely to cause significant graft loss because the implantation sites are beginning to heal.
Contact your surgeon if you notice:
- Active bleeding from the transplant area after rolling
- Visible grafts on your pillowcase
- Significant swelling that worsens after the incident
