Preparing for Your First Laser Hair Removal Session
If you’re booked for your first laser hair removal appointment and feeling a little unsure, this guide is for you. Maybe you’re wondering whether it will hurt, what to avoid beforehand, or whether shaving is allowed. First-time clients often worry about doing something wrong and affecting their results. At Alladerm in Aliso Viejo, we walk every patient through the preparation process step by step, so you feel confident, comfortable, and fully ready before your session even begins.
Preparation is the Key to Laser Hair Removal
Laser hair removal works by targeting pigment in the hair follicle. The laser energy converts to heat, disabling the follicle and reducing future growth. For this process to work safely and effectively, your skin needs to be in the right condition.
Improper preparation, such as recent sun exposure or waxing, can affect results or increase sensitivity. However, preparing correctly is simple when you know what to do.
Step 1: Avoid Sun Exposure Before Your Appointment
Sun exposure increases the risk of irritation, pigmentation changes, and sensitivity during laser treatment. Ideally, avoid direct sun and tanning beds for at least two weeks before your appointment.
Living in Orange County means sunshine year-round, so this one matters. If you’ve recently been to Laguna Beach or spent a weekend outdoors, let your provider know. Always use broad-spectrum SPF daily leading up to treatment.
Step 2: Stop Waxing, Plucking, or Threading
Laser targets the hair follicle, and waxing or plucking removes it temporarily. If there’s no follicle present, the laser has nothing to treat.
Avoid waxing, tweezing, or threading for 4 weeks before treatment. Shaving is completely fine (and encouraged) because it leaves the follicle intact beneath the skin.
Step 3: Shave 24 Hours Before Your Session
This surprises many first-time clients. You should shave before your appointment. Shaving the day before allows the laser to target the follicle beneath the skin without burning surface hair. Avoid shaving immediately before your appointment, as freshly irritated skin can be more sensitive.
Step 4: Avoid Certain Skincare Products
For about 3–5 days before treatment, avoid:
- Retinoids
- Strong exfoliants
- Chemical peels
- Harsh active ingredients
These can increase skin sensitivity. Keep your skincare routine simple and gentle leading up to your session.
Step 5: Arrive With Clean, Product-Free Skin
On the day of your appointment, do not apply:
- Lotion
- Oils
- Deodorant (for underarm treatment)
- Makeup (for facial areas)
Clean skin ensures optimal laser contact and reduces irritation risk. At Alladerm, we’ll cleanse the area again before starting, but arriving product-free helps streamline your visit.
What to Expect During Your First Session
Most people describe laser hair removal as a quick snapping sensation similar to a rubber band. Modern laser systems include cooling mechanisms to increase comfort. Session times vary by the laser areas. Smaller areas, such as underarms, may take 10–15 minutes, while larger areas, such as legs, may take longer.
You may notice mild redness afterward, similar to a light sunburn, which usually fades within hours. Hair doesn’t fall out immediately. It sheds gradually over 1–3 weeks.
A Quick First-Session Checklist
Here’s a simple recap to make things easy:
- No sun exposure for two weeks
- No waxing or plucking for four weeks
- Shave 24 hours before
- Avoid retinoids and harsh skincare
- Arrive with clean, product-free skin
If you’re unsure about anything, just call. We’d rather answer questions than have you stress about it.
How Many Sessions Will You Need?
Laser hair removal requires multiple sessions because hair grows in cycles. Most patients need 6–8 treatments spaced about 4–6 weeks apart for optimal reduction. Consistency is key. Skipping sessions can slow progress.
