Summary

In this engaging video, Dr. Maxfield and Dr. Shaw dive into common myths surrounding hair care, specifically addressing the widely believed notion that shaving makes hair grow back thicker. They explain that shaving only alters the hair's appearance temporarily due to the blunt edges created by cutting it. The duo also debunks this myth with research, emphasizing that hair thickness is more influenced by natural growth patterns and hormones over time. The video concludes with tips on hair removal methods, highlighting threading and laser treatments for those seeking permanent solutions, all while encouraging viewers to share their own myths for future episodes.

Takeaways

• 😀 Shaving hair does not make it grow back thicker. The appearance of thicker hair after shaving is due to the blunt edge of the hair shaft.
• 😀 Hair growth is largely influenced by hormones and natural aging, leading to thicker, coarser hair over time, regardless of shaving.
• 😀 The belief that shaving makes hair thicker has been studied extensively, with research showing no difference in hair growth rate or thickness after shaving.
• 😀 Some hair removal methods like waxing, threading, and laser hair removal can remove hair from the root, but may come with risks like ingrown hairs.
• 😀 Laser hair removal is an effective, permanent solution for hair removal, especially when done in multiple sessions. It targets the hair follicle, preventing regrowth.
• 😀 Electrology, although effective, is harder to find and requires specialized training. It's a more intense, painful option compared to other hair removal methods.
• 😀 Laser hair removal works for all skin tones, given the appropriate settings are used, and can provide permanent results with occasional touch-ups.
• 😀 There are creative uses for laser hair removal, such as designing a permanent 'lineup' for the back of the neck, although it's a permanent style choice.
• 😀 Threading is recommended over waxing for facial hair removal, especially for those using products like Retinol that can make the skin more sensitive.
• 😀 The myths and misconceptions about hair growth are common, and it's important to understand the science behind hair removal for more informed choices.

Q & A

Does shaving hair make it grow back thicker?

No, shaving does not make hair grow back thicker. Shaving cuts the hair flat, which can make it appear thicker temporarily. However, it doesn't change the hair's root or follicle, which is what determines the hair's thickness.

Why does shaved hair look thicker when it grows back?

When you shave, the hair is cut straight across, creating blunt edges. These blunt edges give the appearance of thicker hair. However, the hair itself remains the same thickness, and over time, it will taper back to its normal form.

How do hormones affect hair growth?

Hormones, especially during puberty, can cause hair to grow thicker and coarser. This is a natural process where more hair develops on the body, and it becomes more terminal (thicker and darker).

Is there any scientific evidence supporting the idea that shaving affects hair thickness?

Studies from the 1920s and 1970s have shown that shaving does not affect hair growth rate or thickness. In these studies, people who shaved their hair and others who didn't showed no difference in the hair's growth rate or characteristics.

What methods can effectively remove hair without making it appear thicker?

To remove hair without affecting its appearance, methods like waxing, threading, and laser hair removal are effective. These techniques remove hair from the root, preventing the blunt, thicker look associated with shaving.

What are the risks associated with hair removal methods that target the root?

Hair removal methods like waxing, threading, and electrolysis that target the root can increase the risk of ingrown hairs. While they prevent the appearance of thicker hair, they may cause irritation or ingrowth if not done correctly.

How does laser hair removal work, and is it permanent?

Laser hair removal works by targeting the hair follicle with heat, which damages it and prevents future hair growth. It is generally permanent after several sessions, though touch-ups may be needed in the future.

What is the difference between laser hair removal and electrolysis?

Laser hair removal uses light to target and damage hair follicles, and it works on all skin tones with proper settings. Electrolysis, however, uses electric currents to destroy individual hair follicles and is a more precise but also more painful and difficult-to-find treatment.

What are the advantages of threading over waxing for hair removal?

Threading is preferred over waxing for some people because it doesn’t pull on the surrounding skin. Waxing can irritate the skin, especially for those using products like retinol, which can make the skin more sensitive.

Can laser hair removal be used for other purposes besides hair removal?

Yes, laser hair removal can be creatively used for purposes like creating a permanent hairline or lineup on the neck, offering a more consistent, clean look without regular maintenance.
