PRF (Hair Restoration) Sacramento & Davis, CA

A natural approach to hair regrowth, PRF therapy uses your body’s own healing properties to stimulate dormant follicles, slow shedding, and support denser, fuller hair in targeted areas of thinning or loss.

PRF Hair Restoration Expertise at Davis Dermatology

Hair loss can impact confidence, no matter the cause. At Davis Dermatology, we offer nonsurgical PRF (platelet-rich fibrin) therapy for patients looking to restore hair density using their body’s natural regenerative abilities. Performed in a physician-led dermatology practice, PRF hair restoration is a personalized treatment backed by evidence and clinical expertise.

Understanding PRF for Hair Loss

At Davis Dermatology, we offer Platelet-Rich Fibrin (PRF), an advanced regenerative treatment that uses your body's own natural healing ability to reactivate dormant hair follicles, support healthier hair growth, and improve scalp health.

PRF is created from a small sample of your own blood. Unlike older regenerative techniques, PRF is processed gently and without added anticoagulants or chemicals — allowing it to retain a natural fibrin matrix along with concentrated platelets, growth factors, and white blood cells. This matrix acts as a slow-release system, gradually delivering healing factors to the scalp over time. The PRF is then carefully injected into areas of thinning to encourage stronger, healthier follicles.

PRF helps improve the following concerns:

Thinning hair in the early stages
Pattern hair loss in men and women
Shedding due to stress or hormonal changes
Receding hairlines
Hair density after a transplant

What Makes Davis Dermatology the Right Choice for PRF?

Our team offers PRF hair restoration with clinical precision, using FDA-cleared systems and refined protocols that prioritize results and patient safety. Every procedure is customized for the unique needs of each patient, guided by a deep understanding of hair biology and skin health.

Why We Choose PRF Over PRP

PRF is considered the next generation of regenerative therapy, and it's why we've made it our primary approach going forward. Both PRP and PRF use your own blood to promote healing, but they're processed differently. PRP is spun at a higher speed to separate and isolate platelets from the rest of the blood. PRF is spun more gently, so it retains a natural fibrin scaffold along with platelets, growth factors, and white blood cells — nothing is filtered out or added. That fibrin scaffold is what allows PRF to release growth factors gradually over time, rather than all at once, which supports longer, more sustained follicle stimulation.

Are You a Candidate for PRF?

During your consultation, Dr. Noll will evaluate your medical history, scalp condition, and type of hair loss. PRF tends to be most effective when started early in the hair loss process.

The following are ideal candidates:

Individuals in good general health
Men and women with early-to-moderate thinning
Patients who are not ready for surgery
Those without underlying autoimmune hair loss disorders
Non-smokers or those willing to quit

The whole office is extremely professional and helpful

Dr. Noll, Daniel, and Karla are wonderful. The whole office is extremely professional and helpful. My skin was so damaged from all the sunbathing I did in the 80s, and Dr. Noll has completely changed that. I have had some really bad experiences with doctors in the past, so I get very nervous when I enter any medical facility. This office is so pleasant and relaxing, I don't experience any of my usual anxiety when I go to see Dr. Noll. She is very competent and I trust her completely, 100%. I highly recommend her.

I highly recommend this office

I really like this office, soooo professional. I love the treatments I've had here (botox, fillers, tightening, and laser resurfacing). Prices are reasonable, and Dr. Noll listens and then advises on what she thinks will work best for your budget. She is a great doctor, and I love the results. Her staff are the nicest I've had at a doctor's office and go out of their way to make you feel comfortable, the costs and co-pay are stated right up front ( no surprises). I highly recommend this office.

Her office and staff are top-notch, and I (as a medical professional myself) would highly recommend her to anyone searching for a dermatologist. I no longer live in Davis, but I still drive nearly 3 hours to see her. I couldn't ask for a better dermatologist!

Her staff was also very friendly and helpful

I had my very first consultation with Dr. Noll today, and it was a very pleasant experience. I was a bit nervous, but Dr. Noll made me feel very comfortable, almost as if I were talking to a very good friend. She explained the procedures in a way that was easy for me to understand, and she made me feel very safe in choosing her for my procedure. I would strongly recommend her for any dermatological procedure. Her staff was also very friendly and helpful.

Your PRF Treatment: What to Expect

Consultation – We assess your hair loss pattern, history, and goals to confirm PRF is a good fit.
Blood Draw – A small sample is drawn, similar to a routine lab test.
Gentle Processing – The sample is processed without anticoagulants to preserve the natural fibrin matrix, platelets, growth factors, and white blood cells.
Injection – The PRF is injected into areas of thinning across the scalp.
Return to Normal Activities – Most patients resume their day immediately, with only mild scalp sensitivity for a day or two.

Healing and Hair Growth Timeline

There is little to no downtime after PRF therapy. Mild swelling or scalp sensitivity may last one to two days. Because PRF works with your body's natural healing process, results build gradually. Most patients notice reduced shedding within the first couple of months, with visible improvements in hair density and thickness developing over three to six months as follicles respond and new growth cycles begin. A series of sessions, spaced several weeks apart, is typically recommended for best results.

Other Hair Loss Treatment Options

Topical and oral medications – Support regrowth and prevent future loss.
Microneedling RF – Enhances product absorption and scalp health.
Low-level laser therapy – Uses light energy to stimulate follicles.
Hair transplant referrals – For patients with advanced hair loss.
