Why two clients with identical head circumference may need entirely different prosthesis patterns Hair & Wig Science Series | HIASTI Clinical Education Two women sit for consultation on the same afternoon. Both measure 22 inches around. If circumference decided the pattern, they would leave with the same unit. They will not. One needs a deeper occipital curve and a shortened front-to-back. The other needs recessed temple points, extra rise through the crown, and a base that c

Locs pull, and traction alopecia is what brings many of our clients to us. We build loc systems by hand on medical silicone foundations, so the look of a mature loc journey carries no tension on the scalp at all. Our guide covers every size we make, how to pair loc type with cap type, and what oils do to a base over time.

New York's new textured hair curriculum requirements take effect today. It is the right change, and it is worth understanding precisely what they do. Senate Bill S6528A was signed into law on November 17, 2023. The Department of State then developed the detailed curriculum amendments needed to implement that mandate through its Appearance Enhancement Advisory Committee and the state's rulemaking process. The final amendments were adopted in July 2026 and take effect September

The wig that started this conversation. Vintage waves, side swoop, ready to wear. We finished this readymade wig, set it down, and did what we always do. We looked at it and asked each other who it reminded us of. Her name came up. Then the memories started. She was our client for more than fifteen years. She has gone to her heavenly home. We are keeping her name to ourselves, but her story is too good to keep quiet. She wore lace systems. She never had sensitive skin, she li

The questions clients ask us most, answered without the jargon People rarely walk in asking about biology. They walk in asking whether this is normal, whether it will stop, and whether it will come back. Those are fair questions and they have real answers. Here are the ones we are asked most. One word will make the rest of this easier. The follicle is the tiny structure in the skin that produces a hair. Almost everything on this page comes down to what is happening to the fol

What sets the ceiling, what decides whether a fibre survives to reach it, and where care genuinely changes the outcome She tells you her hair will not grow past her shoulders. She has said it for years, and she believes it about herself the way people believe things about their own bodies. Often, her hair is growing. It is not surviving long enough to show. T

Why CCCA and frontal fibrosing alopecia require a different foundation, a different attachment, and a different plan A woman sits in the chair and tells you her crown has been thinning for six years. She has been told it is breakage. She has been told it is stress. She has been told to stop wearing her hair up. Somewhere in there, someone sold her a topper with pressure-sensitive clips and told her to wear it every day. Look closely at the vertex. The skin is smooth and sli

What the published research actually says, and why the misinformation matters clinically Hairline Illusions | Hair Loss Awareness Month Most of what people believe about hair loss did not come from a clinic. It came from a relative, a stylist, a comment section, or a product page that needed the reader to believe something in order to sell them something. August is recognized as Hair Loss Awareness Month, and the American Academy of Dermatology uses the observance to direct t

For families paying out of pocket, there may be no room in the budget to purchase twice. What to ask about foundation thickness, ventilation, attachment, hairlines, hair quality, repairs, and maintenance before you buy.

Living with alopecia areata can affect more than hair. This guide explores scalp sensitivity, sleep comfort, friction, dryness, sleep caps, and cranial prostheses, with practical ways to make rest more comfortable.

The wooden mount and the setting compound 3,400 years ago, a wigmaker in Thebes solved a scalp protection problem we are still engineering around today. British Museum EA2560 is one of the most intact wigs ever recovered from ancient Egypt. It came from the west bank of Thebes and dates to roughly 1400 BC. It was found in its original box. When a professional wigmaker examined it in 1975, the finding was that the construction standard matched a good modern wig. Here is what t

Why Foundation Design Must Begin With Living Tissue Hair & Wig Science Series | HIASTI This article introduces the clinical framework examined in The Science of Wig Foundations: A Clinical Guide to Scalp Health, Volume One of the Hair and Wig Science Series. A cranial prosthesis is not made for a head. It is made for a scalp, and the difference between those two statements is the difference between a unit that serves a patient for years and one that has to be abandoned in six

It looks like this. A client commissioned us to build not one but two custom wigs, each roughly 70 inches (178 cm) long. She lives outside the United States and needed hair that would last for years with minimal maintenance, which meant every decision had to prioritize durability and integrity over shortcuts. The commission was a significant investment, and the work behind it explains why. Sourcing took three years. More than 33 raw-cut ponytails were collected, and only 15 m

HAIR & WIG SCIENCE SERIES A HIASTI Clinical Education Publication Peptides and Hair Loss What the Research Actually Shows An evidence review of the peptides marketed for hair loss and graying, organized by what the published research demonstrates and where its limits are. Peptides are short chains of amino acids, and many act as signaling molecules that influence how cells behave. Several are marketed for hair. The strength of the evidence behind them varies widely from o

Why medical wig planning must be based on scalp condition, material selection, documentation, and professional judgment In the hair replacement industry, the words cranial prosthesis, medical wig, lace wig, and hair system are often used as if they mean the same thing. They do not. A cranial prosthesis may be custom, cosmetic, insurance-related, post-surgical, adhesive-free, lace-based, silicone-based, vacuum-based, or medically planned. But not every cranial prosthesis shoul

Pain is not part of wearing a wig. When a wig causes pressure, burning, headaches, itching, soreness, or tenderness, the scalp is signaling that something is wrong. A wig should feel secure, not painful. It should not leave anyone counting the hours until they can take it off, and it shou

Industrial Prostheses, Sensitive Scalps, and the Standard Patients Deserve There is a hard truth in our field that does not get said often enough. The wrong hair system on the wrong scalp is not a cosmetic problem. It is a clinical one. Systems like the three shown here are often marketed or supplied to people experiencing medical hair loss, including cancer patients, alopecia patients, burn survivors, and others with scalp compromise. Each piece was photographed after normal

Protecting the Scalp Under an Attached System A Professional Guide to Clips, Microlinks, Sew-Ins, and Adhesives Hairline Illusions Arts, Science, and Technology Institute When we attach a topper or hair system to a client, we take on responsibility for more than the hair they see. We become responsible for the skin underneath. The scalp is living tissue, and every attachment method, clips, microlinks, sew-ins, and adhesives, places its own demands on that tissue. A method tha
