The slick back bun has become one of the most copied hairstyles around, and few people are as closely linked to it as Perrie Sian. REHAB., the haircare brand known for its single-dose hair oil capsules, has worked with her on Rescue & Revive, a limited-edition collection that includes everything needed for her signature sleek look.
The range covers scalp care, heat protection, styling and lash and brow care, all in a warm fragrance of amber, vanilla, soft musk and coconut. Below we look at each product, what it does and whether the full set is better value than buying pieces individually.

The Full Collection
The full Rescue & Revive Collection brings together six products: the Pre-Wash Hair Oil, the Hair Milk Conditioning Heat Protection Spray, the Smoothing Stick, a Slick Back Smoothing Brush, the Matcha Lash & Brow Serum and a set of Hair Bands. It all comes in the REHAB. Vanity Case. At the time of writing, it was priced at 75 pounds, down from 130 pounds. Buying the four main products separately would cost 99 pounds, so the set also saves money if you want most of the range. See the full collection.
Step 1: Pre-Wash Hair Oil
The routine starts at the roots. Each pre-dosed capsule contains pumpkin seed, black seed and rosemary oils with amla and eclipta extracts. REHAB. designed it to support scalp health and fuller-looking hair while conditioning dry, damaged or over-processed lengths. Apply it to the scalp, focusing on the parting and hairline, massage it in, then smooth what is left through the ends. Leave it for four hours before washing, once or twice a week. The empty capsule dissolves in hot water.
Step 2: Hair Milk Heat Protection Spray
Next is REHAB.’s award-winning Hair Milk in the limited-edition amber fragrance. It is a lightweight leave-in conditioner that protects against heat up to 230C. It also helps detangle, smooth frizz and lock in moisture for up to 72 hours. Shake it, spray it evenly through wet hair, brush through and blow-dry or style as usual. It can also refresh waves and curls between washes, and REHAB. says it suits all hair types, including fine hair.

Step 3: Smoothing Stick for the Slick Bun
The Smoothing Stick is the product for the sleek look itself. It is a compact styling balm with flexible hold and high shine, made with mineral-derived wax and jojoba, plum and camellia seed oils. Brush hair into place, glide the stick over flyaways and the hairline, then brush through. Add more layers for stronger hold. It is small enough for a handbag or gym bag, which makes touch-ups easy.
Step 4: Matcha Lash & Brow Serum
The collection also includes a limited edition of REHAB.’s best-selling lash and brow serum, now with a mascara-style applicator. It combines a peptide complex with matcha green tea extract, panthenol and hyaluronic acid to condition lashes and brows for a fuller-looking result. It is formulated without prostaglandins. Apply it morning and night to clean, dry lashes and brows. REHAB. advises a patch test before use.
How to Recreate the Slick Back Bun
- On wash day, treat the scalp and lengths with the Pre-Wash Hair Oil and leave it for four hours before shampooing.
- Spray the Hair Milk through wet hair, brush it through and blow-dry smooth.
- Use the precision tip of the Slick Back Smoothing Brush to part and section the hair.
- Brush the hair back into a bun or ponytail and secure it with a hair band.
- Glide the Smoothing Stick over the hairline and flyaways, then brush through to finish.
The same steps work for a sleek low ponytail. Keep the Smoothing Stick in your bag for touch-ups later in the day.
Who Is This Collection For?
- Anyone who wears their hair in sleek buns or ponytails and wants a neat finish.
- People with dry, stressed or over-processed hair who heat style regularly.
- Fans of Perrie Sian looking for her go-to products in one place.
