Razor Tool and Frizziness

Razor, used to cut hair
 
Q: I am not a stylist, so please bear with me as I try to phrase my question. My daughter was given a long shag cut. The stylist used a razor to thin out the back and sides. All of a sudden it seems like her hair is frizzy or damaged or something to that effect. Could frizziness or damage occur while using a razor?
 
A: Yes, a razor tool can directly cause frizziness and damage if it isn't used under the right conditions. While razor cutting is a popular technique for creating the soft layers ideal for a shag, it requires precise execution to avoid harming the hair.
 
Because a razor cuts the hair shaft at an angle rather than straight across like shears, it leaves the ends exposed. If the stylist used a dull blade or attempted to razor the hair while it was dry or insufficiently wet, the blade scrapes and drags along the hair shaft instead of slicing cleanly through it. This shreds the protective outer layer of the hair, leading to split ends, rough texture, and immediate frizz. Furthermore, over-razoring or cutting too high up the hair shaft creates tiny, short hairs underneath that push through the longer hair, giving the appearance of persistent frizz and flyaways.
 
Beyond direct physical damage from the tool, the razor is generally not recommended for very curly or coarse hair types, as tapering the ends often disrupts the natural curl pattern and promotes puffiness. However, even on straight or wavy hair, thinning it out significantly leaves the remaining hair sparser and more susceptible to everyday styling damage.
 
While thick hair provides built-in weight and natural resilience against styling and environmental factors, thinned hair reacts much more quickly to heat and weather. When a woman is used to how her thick hair responds to styling and suddenly has thinner hair, she can unintentionally cause damage by not altering her routine.
 
When you have your hair thinned you should keep the following adjustments in mind:
 
• Reduce Heat: Lower the temperature on hair dryers and hot tools, as lighter, thinned ends dry out and burn much faster.
 
• Watch the Weather: Be aware that environmental factors - such as humidity, wind, or dry winter air - will have a much greater effect than they did on thicker hair.
 
• Adjust Haircare Products: You may need to change your choice of shampoo and conditioner, as thinner hair can be overly stripped by strong shampoos or weighed down by heavy conditioners.
 
• Switch Up Styling Products: Hair responds differently to styling products once thinned. You may need lighter hair products, or a tiny drop of lightweight hair oil/anti-frizz serum on the ends to help seal damaged tips while they grow out.
 
If the ends of the hair were severely frayed by a dull blade, a minor trim with traditional shears might be necessary to clean up the damaged tips.
