Hair StimulationAuthor: Dr. Gordon Sasaki
Although hair transplants remain the most effective solution for balding and thinning hair, many patients are interested in regenerating hair growth without surgery. Our director Dr. Gordon Sasaki has been a clinical investigator and an early adopter for alternative methods of stimulating the growth of existing hair in men and women. He is also on the board of the Aesthetic Stem Cell Society. At Sasaki Advanced Aesthetic Medical Center, he offers hair restoration with platelet-rich plasma (PRP) for Los Angeles and Pasadena patients.
Microneedling with PRP
Hair loss in both men and women creates a perception of aging and a loss of vitality. To understand how hair loss is treated, it is helpful to first understand how the hair grows.
Types of Hair
In a typical healthy adult, there exist about 100,000 hair follicles. These hairs can be grouped into the following 2 distinct types:
- Vellus hair is fine, short, and light colored; usually found on the forehead and sides of the face in front of the ears.
- Intermediate hair is longer with more pigment than vellus hair.
- Terminal hair is coarser, longer, and distinctly pigmented; and grows on the scalp, eyebrows, upper lip, chin, chest, arms, legs, and pubis.
The character and texture of hair vary in color, length, thickness, direction, and density, depending on the stage of development and location, as well as the person’s age, gender, and ethnic background. Hair characteristics are also influenced by environmental factors (sun exposure) and body metabolism (hormones, iron, and thyroid levels).

Phases of Hair Growth
Hair on a non-balding scalp is found in the following 3 basic phases of hair growth:
- Growth phase: 90% of the hairs are in the growth phase at any time and remain about 3 years.
- Regression phase: Lasting only 2 to 3 weeks, during this phase the bottom of the terminal hair shortens and separates itself from its blood supply.
- Resting phase: This final phase lasts about 3 to 4 months, after which the hair starts growing back to its original self.
When a terminal hair is unable to regenerate, thinning and balding occurs in the scalp.
Male Pattern Baldness
Male pattern baldness, technically called androgenetic alopecia, is a hereditary condition that is characterized by a progressive loss of hair from the top of the head until only the fringes remain on the sides and the back of the scalp. Hair loss in men is generally due to a breakdown product of the male hormone testosterone that causes the hair follicle to irreversibly wither and die.
Female Hair Loss
Female hair loss is characterized by either a global thinning of hair or spotty loss of hair, leaving the frontal hairline intact. The causes of female hair loss are not understood and are variable in contrast to that found in male pattern hair loss. Stress, hormonal changes, immune alterations, and low levels of iron are believed to be associated with female alopecia.
Common Treatment Options
Today, there are a variety of treatments that can achieve modest results in slowing hair loss and promoting regrowth on the crown, including:
- Topical solutions such as Rogaine® and Revivogen®
- Tablets such as Finesteride® and Dutasteride
- LED red light therapy
The drawback is that when these types of treatment are stopped, hair loss resumes.
Hair Restoration with PRP
Platelets in the blood contain growth factors that facilitate the healing and regeneration of various tissues in the body. Platelet rich plasma(PRP) is a serum of concentrated platelets that, when reintroduced into the body stimulates its natural rejuvenation process. As a clinical investigator and consultant in the use of PRP in aesthetic procedures, Dr. Sasaki has been actively involved in investigating the safety and effectiveness of stimulating hair growth with PRP in men with early androgenetic alopecia. Treatment options, performed on thinning or balding areas, include:
- Injecting processed fat cells enriched with PRP into the scalp
- Performing microneedling of the scalp and then massaging in PRP
With these techniques no downtime is required. While experiences vary, hair growth typically increases, or hair loss slows down. Patients typically see noticeable results about 3 months after treatment. A series of 4 sessions 1 month apart and then 4 months apart for 1 year is usually needed for optimal results.
