Final answer:
Tape-in extensions and micro-rings are recommended for fine, limp hair due to their lightweight nature and even distribution, avoiding tension and potential damage.
Step-by-step explanation:
The best method of attachment for clients with fine, limp hair is typically the use of lightweight extensions and a gentle attachment method. Tape-in extensions are often recommended because they are light and distribute weight evenly across the scalp, minimizing damage and tension to the delicate hair. Another suitable option might be micro-ring extensions, which are applied without heat or glue and can be adjusted easily as the hair grows. However, they must be applied by a professional to avoid undue stress on the hair. It is essential for individuals with fine hair to avoid heavy extensions and methods that can create too much tension, like tight braids or heavy wefts attached with glue or heat, which can lead to breakage.
