Keratin treatments can look good on 4C hair, but it depends on your goals and how the treatment is applied. Here’s what to know:

1. What Keratin Does for 4C Hair
- It smooths the cuticle, making hair appear shinier and less frizzy.
- Reduces tangling and makes hair easier to manage.
- May slightly loosen the curl pattern, depending on the formula.
2. Pros
- Gives hair a sleeker, polished look.
- Can make heat styling (silk press, blow-drying) last longer.
- Helps reduce breakage from constant detangling.
3. Cons
- Some keratin treatments contain formaldehyde or strong chemicals, which may cause heat damage or texture loss if done improperly.
- Results are not always uniform on tight 4C curly hair—some areas may straighten more than others.
- Overuse can weaken strands over time.
4. Best Approach for 4C Hair
- Opt for formaldehyde-free or low-formaldehyde formulas.
- Always have it done by a professional familiar with natural hair.
- Deep condition regularly and avoid excessive heat afterward.
