An old hairbrush is usually a mixed-material personal item. Its hygiene and condition matter before reuse, donation, recycling, or trash.
Keep a sound brush for non-personal cleaning, if appropriate. Do not assume a groomer, veterinary clinic, charity, or recycling program accepts used brushes.
Check Hygiene and Condition
- Unused and packaged: ask a recipient whether it accepts personal-care items.
- Used but sound: keep it for personal or non-personal cleaning after following the maker’s care directions.
- Cracked, moldy, pest-exposed, contaminated, or shedding parts: keep it out of donation and follow local trash guidance.
- Specialty material program: confirm the complete brush, brand, and condition before mailing or dropping it off.
Can Hairbrushes Go in Curbside Recycling?
Usually not unless your local program specifically lists them. Brushes combine a handle, bristles, cushion, adhesive, finish, and metal pins.
EPA says local acceptance controls recycling. A plastic code on the handle does not mean the complete brush belongs in the bin.
Do not pull out bristles or metal pins unless a verified receiver requests separation. Small parts can be unsuitable for curbside sorting.
Reuse a Sound Brush at Home
A brush retired from hair care may clean lint from fabric, dust sturdy surfaces, or help with another non-food task.
Choose a task that fits the brush and its previous use. Do not use a contaminated personal brush on dishes, food surfaces, children, or animals.
Follow the maker’s cleaning and drying instructions. Water, heat, and disinfectants can damage wood, cushions, glue, finishes, or natural bristles.
Ask Before Donating
Do not assume a pet groomer, veterinary clinic, shelter, school, or charity wants a used hairbrush.
Ask the individual organization what condition and packaging it accepts. Many recipients may limit personal-care items to new, unopened products.
Describe whether the item is unused, used, cleaned, wooden, plastic, natural-bristle, or mixed material.
Check Brand or Specialty Programs
A manufacturer or specialty program may accept named personal-care products. Verify the exact brand, item, condition, fee, shipping, and current program dates.
Do not mail a brush based on an old blog post. Program terms can change, and a collection for beauty packaging may exclude tools.
When Trash Is the Route
If no appropriate reuse or verified collection route exists, follow your local household-trash rule.
Contain broken pins or sharp handle pieces as the hauler directs. Do not burn finished wood, plastic, rubber, or adhesive parts.

Questions People Ask
Can You Give an Old Hairbrush to a Pet?
Only if it is sound, suitable, and kept for your own animal with appropriate cleaning. Do not donate it without the recipient’s approval.
Can You Compost a Wooden Hairbrush?
Not as a complete brush. Finish, glue, cushion, bristles, and metal parts can make it unsuitable.
Should You Boil a Hairbrush Before Reuse?
Do not use a universal cleaning recipe. Follow the manufacturer’s material-specific care instructions.
